  • 3. The author would like to dedicate the whole work to his beloved parents
  • 4. The whole manual is divided into three part: Beginning, Intermediate and Expert. Under Beginning part the Basic Geometry- co-ordinate system, loading, supporting, defining and Analysis will be shown for various types of structure; when under Intermediate part both analysis and design will be shown for various types of structure in static linear method. Under Expert part dynamic analysis method will be discussed with sequence. Remember one thing that learning a StaadPro analysis software is a practice work whereas this manual will act as a guideline.
  • 5. This page is intentionally kept blank
  • 6. Part: Beginning 1. Introduction to Fundamental Options: - Open StaadPro A window will arrive similar to picture Choose your Length and Force unit properly; Give your File Name and Location. Press Next and Another window will arrive similar to this
  • 7. After pressing Finish another window similar to this will arrive Fundamental options (1)Unit: Unit can be changed anytime during working Input Unit Display Unit -Press Input Unit and a window will arrive similar to this
  • 8. -Again if you want to change graphical display unit press Display unit You can change unit, label and their position; It is not so important. (2)Measurement: It is an essential option as you have to see the distance during working; All this options are used to see the dimension, changing the lebel and symbol, changing the scale, adding text, showing cut section and returning previous position. (3)Various views: To work with the job we have to change the view of the structure several time;
  • 9. All this options is used to see the view of structure from various side Rotation can be done by rotating the option To zoom the structure and return to previous these are required If you want to return the whole structure use this To see the 3D render view use (4)Various Selection: Selections are found for various part such as node, beam, surface, plate, solid. If you want to see a particular part of the structure then select the area
  • 10. Go to view and do the same Here is your desired part to edit; To return to main structure press Display whole structure
  • 11. 1 Now another selection method is discussed; You can use menu method to select those desired part 2.Creating Structures: You know a structure such as beam, frame, truss, grid etc. can be create by three method: (a) Snap method/Manual drawing (b)Co-ordinate plotting (c) Structure Wizard method/Auto method Now we will draw a beam by Snap method; Snap method is useful when you are going to draw a truss or a customized structure
  • 12. This is the window for Snap Node method drawing; You can choose Plane at which you are going to plot your structure; Angle of Plane can be changed; It is not so important Grid Origin should be (0, 0, 0) Construction Lines can be increase or decrease by changing the number; As you are looking two 10 at X and Y; Change it and see the deference. Again All other option is given for view customization Now click at Snap Node/ Beam and return to the graph and try to add two point according to measurement. 1
  • 13. If you add a point and create a line it will be look like such as given picture. Now another structure- Frame will be created by Co-ordinate method; To do this you need to use the Table shown below where you can plot coordinate (X, Y, Z) for a Node then after plotting some Node such as this way primary work will be done 3 4 2 1 1 2 3 4
  • 14. By giving the (X, Y, Z) value a Node will be created according to Input as you are observing through the picture. Beam can be created by Beams Table ( By Providing Node A and Node B number but another Beam drawing method is proved easier than this; 1 You can simply use Add Beam option shown by 1notation in the picture and add those node manually. Now to complete the structure further work is required; You can copy and paste the structure and a Table will arrive for it. Now first select beam selection (Notation 2) and select your desired parts. 2 3
  • 15. Now to do the Copy and Paste command, first you need to select the part you want to copy than press Ctrl+C and then press Ctrl+V; A table will arrive; Choose your X, Y or Z distance to copy it Before Copy-Paste Operation ----------------------------------------------------------------------------------------------------------------------1 After Copy-Paste Operation 2 Same way you can cut and paste all these parts.
  • 16. Now how to use the structure wizard will be shown and discussed; Press it to get the Table After Pressing a new window will found similar to this Here various types of division of Structures is given for choice Here various types of Structures is given under each Main division for choice
  • 17. Choose your structure and you can also edit it, I mean you can chage its dimension by its customization Table which will arrive after you click in a particular structure. Follow my work; I choose Frame Models as my Main Division and Bay Frame as my subdivision; After pressing a Table I found similar to shown below Frame Models Bay Frame Bay Frame- Table You can change, edit and modify by this table shown above. Here by this Structure Wizard many type structure could be build easily within a moment. You can build bay frame, grid, beam, circular structure, various types of Truss etc. Once you got your structure then you have to merge it StaadPro model. Do it by shown procedure and a table will be arrive.
  • 18. 1 The table will indicate your desired co-ordinate at which you want to keep it. Once it is plotted your structure creating procedure is finished. **You can give/ provide a structure, which has only length and width, its height by using Translation Repeat option. Select your desired part and press Translation Repeat than a table will arrive where you can choose the repeat direction and number of step and connecting command (Link Step) Two picture are given to let you observe the difference between before and after translation
  • 19. 1 ---------------------------------------------------------------------------------------------------------------------- 2 3.Support Page: Now you have to provide support at your end point of the structure. Support is important as they determine reaction, deflection and all other structural facts.
  • 20. In left side a structure is given without support; You see there are no support below the structure. Remember in 3D Render View you cannot see the support. To establish support you have to create support first by pressing Support Page and a Window will arrive simultaneously; 1 2 4 3
  • 21. By doing the work sequence you can make support 2 which is a Fixed Support which have 6 reaction and no deflection. You can also create Pinned/ Hinge Support which has no moment but three reaction; You can create Spring, other support by knowing their support condition, reaction and strength; It is not so big deal. Now after creating desired support you have to plot it at desired position to do it you have to select desired node(Node Selection – Active) by mouse and click to assign. Another method is, you can manually plot the support, this time your mouse point will become support like and by clicking at right node you will be able to set the support at its position. It is not so big deal. You can do it easily if you practice it. Fixed Support Hinge Support Node with Fixed Support Node without Support
  • 22. 4.Member Identification: Member Identification means giving the property of the member – beam, column, slab, shear wall etc. For flexural and axial concrete member it is called ‘Define’ For flexural and axial steel member it is called ‘Section Database’ For area, plate or surface section it is called ‘Thickness’ Property Page When you will click it, a window will arrive similar to this Using this you can create new section and change the Beta Angle Now when this Property window is found, click in ‘Define’ Another window will arrive Similar to below; Now follow the command sequence 1-2-3-4-5 And you will get your first rectangle concrete section of 12” X 6”
  • 23. 3 2 4 5 1 Once you created the section than you must assign it to the required/ desired part of the frame, beam or truss; Assigning job is similar to support assigning job; You must select the members which will be define manually by hand selection or automatically by select menu. See the similarity through the Table given below.
  • 24. Your Section Assigning Options Assigning Command Selected Member Now lets talk about Beta Angle; Sometime we need to plot out section in such angle with the standard axis, then Beta Angle is need to be used. Beta angle command Assigning Command Assigning Command
  • 25. Now see the difference between before giving Beta Angle – 20 degree and after giving Beta Angle – 20 degree. Before giving Beta Angle – 20 degree: No Angle; Just longitudinal along its geometry
  • 26. After giving Beta Angle – 20 degree: 20 Degree Angle with respect to its geometry The discussion for ‘Defining’ a Concrete made flexural and axial member is finished. Now let’s talk about ‘Section Database’. Section Database is done for ready made or available in market Steel section only. I will use it now, click in Property Page and wait for table. Click in section data base. 2 3 1 4
  • 27. Maintain the sequence 1-2-3-4 1- Click section database 2- Choose your Code & Section than Add it 3- The desired section is Added & ready to use 4- Select your member/grid and click ‘Assign’ Introduction to Section Database is completed here; Now we will discuss about Area, Plate, Surface thickness. It is required for any solid area depended formation; Making and designing slab, Shear wall, Wall, Surface etc. can be by done this option. You must have created surface/ Plate/Solid etc. before you are going to define it. To make it you can use Mesh, Plate, Surface. Choose one of them 1. Mesh – For precise slab design Mesh 2. Plate – For fast slab design Plate 3. Surface – For ground, area, slab etc. Surface Plate is used to represent the shear wall
  • 28. Once plate is created then go to property page and choose thickness; 1 4 2 3 Follow the sequence and assign the thickness to the desired plate. 5. Load Page: The structure is completed and section is defined; Support is also determined so you can assign ‘Load’ Structure without any load
  • 29. Generally Dead Load, Live Load, Wind Load and Seismic Load are concerned. Make sure everything (preliminary activity) is done then go to ‘Load Page’ A window will arrive after clicking on it (Shown below) 1. New Load Table 2. Load Page 3. Load window - From Load Window -> Load cases details -> Add ThenNew Load Table will appear. Choose Dead Load from Loading type drop menu Give title Dead Load and Add it Again do the same for Live Load, the difference are present in choosing Live Load from Loading type and giving title Live Load - Now see the Table shown below, it should be look like this…..
  • 30. See under Load Cases Details Dead Load and Live Load are present now all you have to do is click in Add and wait for another table. New Table, Arrived after clicking Add
  • 31. Now under Self Weight Add it, again click in Floor Load; Give Load pressure 130 kip/sft & Define Y Range Minimum 0 ft Maximum (your highest floor) 30 ft And Add it From next picture see the difference between before loading and after loading.
  • 32. Repeat the whole procedure for Live Load again. Now Let me talk about Wind Load Wind Load is a typical load for all high rise building; Follow the procedure to make a Wind Load in StaadPro 2006 for a typical 4 -storey 3 X- bay and 3 Y-bay frame building. Building in X –Y Plane Front View
  • 33. First Action: Make your structure and do not forget their co-ordinate. 20,20 0,20 10,20 Z- Axis 0,0 10,0 20,0 X- Axis Now Define all member and assign support to the end node from X- Y plane. Second Action: Go to Load Page and let the table arrive; Now you have to give the definition of the Wind Load. Click Definitions and then Add Wind Definitions Then Press Add
  • 34. After Clicking Add another Window will arrive; Write Wind in X and then again press Add. A Load called Type- 1 will be added under Wind definition Now do same for Wind in Y so that another load called Type- 2 may added under Wind definition
  • 35. Now Close it and then click in Type- 1 so that another window may arrive which is shown below. Full fill it. Height of Building (1-99) Intensity of Wind You can find the Intensity by using Excel where Cz, Cp, Ct etc. are used to get design force and pressure Check Excel document Another way is Click in button below. shown above. A window will arrive shown Now press OK
  • 36. Now see your given chart is full filled But your building is 2 storey and 20 ft high so keep 20 feet data only. Press Add and give factor 1 and Add again. Now press Load Cases Detail. Click in Add a Window will arrive shown below Provide Dead in Loading Type and give name Dead Load in Title And Add. Do the same for Live Load, Wind Load in X, Wind Load in Y while Loading Type will be Live, Wind and Wind respectively. Now Close it and watch your window should be like below.
  • 37. Load Cases Details: Dead Load, Live Load, Wind in X, Wind in Y Now your wind loads are defined but you have to assign it to the concern structure. How to assign the wind loads? At first click in Wind in X and then press Add A dialogue box will arrive similar to this. Now see and follow the notation 2 1, 2, 3 Notation 1: Select Wind Load Notation 2: Define 1 3 X range as your Wind is in X direction After putting correct
  • 38. data as the Table is filled in right, your structure will be look like the picture shown below. Add it Do the same process for Wind in Z. Remember one thing in StaadPro
  • 39. X is horizontal, Y is vertical and Z is perpendicular to the screen. Now it is time to discuss about Seismic Load or Earthquake. To design or analysing a structure with seismic you must entry seismic first (Before Dead Load and Live Load) otherwise it will not work. How to define the wind loads? Go to Commands- Loading – Definitions – Seismic Load - UBC 1994
  • 40. A window will appear similar to this; Fill it similar to the table Zone – 0.15 Importance factor – 1 Rw in X – 5 Rw in Z – 5 Site coëfficiënt – 1.5 Ct value – 0.03 for RCC 0.075 for Steel And Add it. It will be added under Seismic Definition Select it and press Add another table will appear Add
  • 41. Add it again under self-weight Now go to Load Cases Details and Add Seismic in X and Seismic in Z while loading type is Seismic Seismic X and Seismic Z are added
  • 42. Now select Seismic X then Add a table will appear shown below Fill it as shown in above and add it. Do the same for Seismic Z; Then see the Table again. It is ready to be analysed.
  • 43. Now let’s discuss about how to give UDL, point load, Concentrated moment First make a 2D Frame similar to below. 2D Frame To do this follow the steps - Draw line - Provide support - Define member Under Load Cases Details There are 2 Dead Load – Load Case 1, Load Case 2 First we will create point load.
  • 44. To make it select Load Case 1 and press Add so that a window will arrive shown below Select it Do the same in the window to get a 10 kip point load which will be 5 feet above from the bottom point in Y direction. You can see it is already added under Load Cases 1
  • 45. It is ready to assign in the column; Select the member at left side and assign it. Your structure should be look like this 10 Kip concentrated Load is given Now let’s talk about concentrated moment. Now click in Load Case 1 and press Add. A table will arrive and go to member load then go to concentrated moment; A window will open similar to this. Do the same and Add it. This moment will be added under Load Case 1; You can assign it in a column now.
  • 46. Your structure will be like this. 10 Kip Point Load 5 K-ft Moment Perspective View Now it is time for discuss about UDL Go to Load Cases Details – Load Case 2 – Add – Member Load – Uniform Force A table will arrive shown below and fill it by same way
  • 47. Your UDL will appear under Load Case 2 and it is ready to assign; Select the beam ( There is a Beam in your 2D Frame) and assign it. See your UDL in the 2D Frame. 20 kip/ feet Uniform Load Using same process you can provide - Uniform moment Trapezoidal Load and Moment Hydrostatic Linear Varying Load Snow Load Vehicle Load Dynamic and Time response etc.
  • 48. Load Combination: `When you assign Dead Load, Live Load, Wind and Seismic together it should be combined. The way is used to mix up all these Load is called Load Combination. There are many types of Combination Now I will provide Dead Load, Live Load, Wind in
  • 49. 6. Analysis: After doing all these pre-analysis activity or you can call it modelling It is time to learn about analysis. After analysis you can see deflection, shear, moment, axial, torsion for each member. You can also see the animation during analysis. Analysis is prerequisite of design for all types of structural member. Follow the step: Commands –> Analysis A window will open after clicking in Analysis Press Ok
  • 50. Now go to Analyze – Run Analysis or press Ctrl + F5 A table will appear; Press Run Analysis Another Window will appear; Use radio button Go to Post Processing Mode and Done
  • 51. Then Result Setup dialogue box will appear Press OK and complete the procedure. You can see the displacement shape & value for both node and beam.
  • 52. If you want its shear, moment, axial, torsion etc. for each member then chapter 7 ( Use of Data and Analysis) 7. Use of Data and Analysis: It is part of Post- Processing when geometry, support and define job are part of Modelling. You can move between Modelling and Post- Processing by using thses two options You can see both value and diagram in StaadPro for all combination that is made by you. Combination Staad Output Click Staad Output to get Output Viewer
  • 53. How to see the axial force in StaadPro? Go to View – Tables and click it Using this Tables you can get any output anytime. To see the axial diagram click in Axial Force Axial Force And to get those value go to Symbols and Levels A window will appear where you will go Loads and Results
  • 54. And after pressing OK your Axial Force will come with value. Use this to get diagram And use Loads and Results to get its values.
  • 55. Part: Intermediate 8. Design of Slabs: Slab is the upper portion of the building. In this Intermediate part we will discuss about Flat Plate. Designing of a slab means calculating its no of steel required and analysis means computing its deformation, shear, moment and its deform shape. When we design a axial or flexural members (i.e. Beams, Columns etc.) then the loads from slab are exchanged in the beams. What does it mean? It means when you design a beams then you have these load to be considered - Self-weight of beam - Dead Load (i.e. Cladding, random wall) - Live Load - Load from Slab And You don’t make the slab using plate, surface etc. Now come to the point- When you design a flat plate then you draw the slab in such a way so that the beam is covered by the slab. Slab Beam Slab- One way & Two way Slab
  • 56. Slab Beam Slab- Flat Plate From above two picture you should understand the difference is made while drawing the these two slab. Now I will design a Flat Plate in detail; Just follow the steps I will design a Flat Plate when Dead Load is 120 pcf, Live Load is 110 pcf Using the geometry daw the span and bay; Make a two storey building. Now let’s define it; Go to property page – Define –
  • 57. After doing this you will make a 6’’ by 6’’ Concrete section; Assign it in your frame and see the 3D rendering View
  • 58. Again using Property Page you will define a new thickness. After clicking the Thickness a window will arrive. If you do the same you will get a thick surface or you can call it Plate which is ready for assign as a Slab. Did you notice that plate thickness is also 6 inch similar to defined beam section which is done in above portion. This 6 inch plate is not ready to be assigned as you did not build the plate. How to build plate? Don’t mash up it with thickness define. You will build your plate by this way. After that you will assign it through definition process which is done by property process. Plate Option
  • 59. Click it and connect 4 node of a area so that it become a Plate. Plate Cursor Plate is making by Mouse Select the Plate Cursor and Select the whole structure and you will select those Plate only. Plate can be Copy and Delete like beams. Your Plates are selected by Mouse Now you have to assign your thickness to your plate.
  • 60. I assigned your thickness in your Frame system; Now see how does it look 3D Render View Now give Load; Go to Load Page and Add two Load Case; One of them is Dead Load another is Live Load. Under Dead Load you add Floor Load and a table will arrive Fill the Table according to this table; When you are working with a Slab you are going to give Load by Floor;
  • 61. Now it is time for analysis and design. To analysis go to command – analysis – Perform analysis – OK (Table) Now Press Ctrl + F5 and Run Analysis; It will take few seconds to analysis. Analysis is not our objective; We need to design it. Go to Commands – Design – Concrete Design A table will open shown below called Concrete Design Table
  • 62. 1 Go to Commands – Choose Design Slab/ Element - Add 2 And this design command will added under Start Concrete Design; 3 You have to assign the slab under this DESIGN ELEMENT; There is a Question Mark. It will remove when you will assign it in proper element; Select the Whole Plate ( using Plate Cursor) and Assign it then this question mark will remove.
  • 63. After Assign action it is changed. Now press Ctrl + F5 ( Analysis); This time it will be designed. In output document you will get the number of steel are required to give stability and safety.
  • 64. 9. Design of Concrete section( full version): In this section a Concrete frame consist of beams and Columns will designed. Steps: (1) Geometry- Creating the frame (2) Support (3) Define those member (4) Load (5)Analysis (6)Design Command (7)Design (8) Output Observation Now let’s do the Geometry portion First create a frame- Node Snap method/ Co-Ordinate Method/ Structure Wizard (Choose one of them) I am going to use Structure Wizard. My structure is shown below: Perspective View Top View
  • 65. It is time to provide Support by support page; I will make and use fixed support. Using Property Page, I will define my member; I will use 12’’ by 12’’ Concrete Section all over (For both Column and Beam) After assign job I structure is similar to below: 3D Render View after assign job
  • 66. It is time to provide load in my structure. Go to Load page and create four load- Dead Load, Live Load, Seismic and Wind Load For Dead and Live Load you don’t have to provide definition. For Wind and Seismic definition is an important fact. Seismic should be first load. All these things are shown in Load Page chapter. Here I made my Load Page and structure: For your help every load page in sequence is shown in next page: So that you can- maintain the load sequence - Choose actual minimum and maximum value of X, Y, Z - Choose accurate load value and type - Check your work
  • 67. Seismic Definition Wind Factor Definition Wind Intensity Definition Seismic Load Case in X: Self Weight For Seismic in Z all these values will remain same except where radio button is X direction, there will be Z direction. Seismic Load Case in X: UBC Load
  • 68. Dead Load- Floor Wind Load Case in X Live Load- Floor For Wind Load in Z all these values will remain same except where radio button is X direction, there will be Z direction.
  • 69. Now see the total summary of your Load work: Load assign job is finished. Now it is time for analysis. Analysis process is already shown in previous pages. To start the Analysis process; Go to Commands – Perform Analysis – OK Then press Ctrl + F5 to complete the process and Run Analysis
  • 70. Choose Go to post processing Mode and Done Another window will open and press OK.
  • 71. Then Node and Beam displacement will arrive in Tabular Form and Diagram In analysis section we discussed about various combination. Combination is done to mix up the effects of various loading together. You can check the displacement for various combination using this option You can see also shear, axial, moment, torsion by Table options Tables
  • 72. You are now in Design stage. Go to Commands – Design – Concrete Design; A window will open This window is called Design Window From Design Window press Command and Add Design Beams and Design Columns Then Assign Design Beam and Design Column to its member. After this you need to pacify some design facts such as Clear Cover, Tie-bar data, Minimum main reinforcement size etc. You can customize or make a new style by Define Parameters
  • 73. Now to complete the Design Process you have to analysis it again. Press on Run Analysis and from new window choose View Output File and Done Now you will get StaadPro Output Viewer window
  • 74. This is total design documents. When you are in post processing section you can see the result and reports which are important to see the displacement, axial, shear, moment, torsion and stresses for beams, columns and plate; Use of report is more important than result. When result give values, Report not only gives value but also provides effects in a report form.
