3. INTRODUCTION
Our project is based on the Design &
Analysis of the G+3 Residental Building.
Analysis is done through using the Etabs.
Notation adopted through out the project is
same as IS-456-2000.
4. CODES
IS-456:2000:Design Code For RCC.
IS-875(PART1):Code For Dead Loads.
IS-875(PART2):Code For Imposed Loads.
IS-875(PART3):Code For Wind Loads.
6. Utility Of Building:Residential Of Building

8. DIFFERENT TYPES OF LOADS ON THE
STRUCTURE
Dead Loads
Imposed Loads
Wind Loads
Live loads
Wind Loads
10. Live Loads
TABLE 1 of IS: 875 (Part 2-1987 provides
imposed floor loads for different
occupancies (Clauses 3.1, 3.1.1 and 4.1.1).
11.
12. Imposed Loads
Imposed also known live loads
Load over the floor i.e load of person
it is calculated as kvn/m2
This load is applied over the length of
structure
13. Winds Loads
Winds is air in motion
Winds loads are calculated according to
IS:87(Part 3)
Internally of wind & exposure are applied
in the direction as required
15. Load Combination
Analysis of a building with respect to dead load and live
load, the code refers following load combination.
1. 1.5(DL + IL)
2. 1.5(DL + Pi + WL)
For seismic load analysis of a building, the code refers
following load combination:
1. 1.5 (DL + 1L)
2. 1.2 (DL + LL +/- EL)
3. 1.5 (DL +/- EL)
4. 0.9( DL +/- EL)
16. For wind load analysis of a building, the code refers
following load combination.
1. DL + L
2. DL+WL
3. DL+0.8LL+0.8WL
17. Design Principle , Assumption & Notation
Assumed
The notation adopted throughout the work is same as in IS 456-2000
The notation adopted throughout the work is same as in IS 456-2000
ASSUMPTION IN DESIGN
Using partial safety factorised loads in accordance with clause 36.4
of IS 456-2000
Partial safety factor for material in accordance with clause 36.4.2 IS
456-2000is taken as 1.5 for concrete & 1.15 for steel
Using partial safety factores in accordance with clause 36.4 of IS

i)Live Load on Slabs = 3.0kn/m2
LIVELOADS:In accordance with IS875-86
ii)Live Load on Passage = 3.0kn/m2
i)Live Load on Stairs = 3.0kn/m2
19. Objectives Of Structural Design
The main objective is to do planning, analysis and design of the
structure having passed all the safety requirements and checks. The
detailed objectives involved are as follows:
To prepare the plan for site (37'×57') west facing for G+3 residential Building with 3BHK
To locate the position of structural elements (column & beam) and get the drawing using AutoCAD 2017
To prepare the 3D model of the structure by using the ETABS-2019 Software for analysis, and design
through the method of linear static analysis.
To Validate the ETABS result by Kani’s method (manually).
To design structural elements like beam, slab, column, staircase and footing as per Indian standard
code IS 456:2000&SP-16.
20. E-Tabs
ETABS stand for extended 3D analysis of building system. ETABS is
an engineering software product that caters to multi-story building
analysis and design. Modelling tools and templates, code-based load
prescriptions, analysis methods and solution techniques, all coordinate
with the grid-like geometry unique to this class of structure. E-TABS is
a software company with its headquarters in London, England.
21. Graphic input and editing for easy and fast model generation
3D generation of the model through plan views and elevations
Advantages of using E-Tabs
Fast model generation using the concept of Similarstories.
Easy editing through the Move, Merge, Mirror and Copy commands.
Fast object creation with one click of the mouse
Multiple viewing windows.
3Dview with zoom and pan capability.
22. Another advantage of ETABS is even after the design, properties of the
members can be updated if required. The following properties can be
update
1. Column Position2 Column Shape
3.Column Size
4.Load Cases
5.Support case
It is very easy to deal with this software and we don't have any best alternative to
this.
23. Auto-cad as an architectural planningtool
Auto-cad as an engineering drafting tool
Auto-cad as a graphic design tool
Auto-cad in 3D Printing
Auto-cad in the fashion industry
Auto-cad as industrial design tool

30. Analysis
Analysis is done by ETabs
Once the loads & load combination are
assigned to the structure, analysis is to
bedone
Analysis is done for RCC structure.

36. Conclusion
Planning of the building and reinforcement details of structural
elements (beam, column, footing, slab & staircase) were drawn using
AutoCAD 2017, thus making it Productive.
Analysis of framed structure for the residential building was done by
using ETABS2019, which is time-saving and effective, as manual
analysis of an entire building takes many weeks tocomplete which
troublesome.
All the structural members are checked to satisfy the serviceability
criteriaand hence providedthe required dimensions for members.
All the members were designed by limit state method, which is more
rational and realistic in comparison with other design methods.
Design and other prerequisites of a building before construction using
software’s and as per IS code provisions gives an approximate
quantity of materials required preventing over expenditure.
