  4. 4. RM Bridge General Training Getting Started – GP – DIN 1-1 1 General The following small example will show all necessary GP and RM definitions for a small bridge structure. All input steps are described in detail and we invite you to follow the pro- cedure as follows to get a feeling for the program use.  Definition: 1. Axes Geometrical definition of the road/rail axes. 2. Cross-section Geometrical definition of the cross-section 3. Segment Several logical units of the structure are represented as “segments”. In this example the main girder for instance is one segment, a pier would be another segment on its own. 4. Structural System (Export to RM) The structural system with all necessary information (bearings, stress flow, …) is prepared for the subsequent run of the structural analysis in RM. The 3-dimensional bridge axis is defined in plan and elevation. The change along the axis is called Station. The Segments are subdivided using Segment points. The cross-sections are assigned to the Segments via the Segment points. The spacing between the Segment points will be Elements, the Segment points will be Nodes in the structural system for RM. The structural system is therefore defined by the axis, the cross-section and the segment. © Bentley Systems Austria

Several ac- tions are available here: Start the program by double clicking the GP icon. First Level © Bentley Systems Austria
  9. 9. RM Bridge Creating a New Project Directory Training Getting Started – GP – DIN 3-2 Create a new project directory A new (empty) work space (directory) is usually created at the beginning. All data will be stored in this direc- tory. The current directory is displayed in the upper left corner. Select this icon to pop up the path selection of the Windows-Explorer. Select the wanted directory. This example is done under C:WORKTraining. Create a new directory (Training). Choose the directory using <Öffnen> Define directory (<open> for English windows versions). Open © Bentley Systems Austria
  10. 10. RM Bridge Creating a New Project Directory Training Getting Started – GP – DIN 3-3 Use <OK> to start the GP application in the selected directory. Start application Confirm © Bentley Systems Austria
  11. 11. RM Bridge Construction of Axis Training Getting Started – GP – DIN 4-1 4 Construction of Axis Axis elements are used to define the axis in plan. For this example the axis is straight. 4.1 Create an Axis Select the button for “display existing axis“ to open the pop-up window for the axis defi- nition. You can either define your new axis by ticking Straight in the pop-up Window which will create an axis with the appropriate length or you untick Straight and RM will create a new axis but not geometrically information are set at the beginning. Both ways are shown below: First Method: The default proposal Define an Axis for axis name (axis1), initial station and in- creasing station- numbering is chosen for this example the Length is set to 60m. <OK>. Confirm The created axis is displayed in the listing of existing axes. Several axis can be defined in one directory. Changing between the axes (activating a new axis) can be done by select- ing (clicking) the wanted axis and hitting <OK>. The currently active axis is shown in the Active information-bar at the left lower corner ( „Axis1‟ in this exam- ple). Select this button to activate the input window for “ground- Your new created axis plan”. is shown here with a length of 60 m. © Bentley Systems Austria
  12. 12. RM Bridge Construction of Axis Training Getting Started – GP – DIN 4-2 Second Method: The default proposal Define an Axis for axis name (axis1), initial station and in- creasing station- numbering is chosen for the example. <OK>. Confirm The created axis is displayed in the listing of existing axes. Several axis can be defined in one directory. Changing between the axes (activating a new axis) can be done by select- ing (clicking) the wanted axis and hitting <OK>. The currently active axis is shown in the Active information-bar at the left lower corner ( „Axis1‟ in this exam- ple). The second method only creates the axis without any geometri- cally information. To define the starting- and end point of your axis you need to go to the “gound plan” and define there your coordinates. (see chapter 4.2) 4.2 Constructing an Axis in Plan  Axis in plan: straight line: Station: 0-60 m Select this button to activate the pop-up window for “ground plan”. Select P0 from the up- per menu in order to define the starting point of the axis in the “ground plan”. Select the coordinates for the starting points (X = “east, Y = “north”). . © Bentley Systems Austria
  13. 13. RM Bridge Construction of Axis Training Getting Started – GP – DIN 4-3 Confirm The default set is ok for this example, point P0 has the coordinates (0.0/0.0). The new axis points in the X-Direction, no angle needs to be defined. After input confirmation the point with the specified direction will be visible on the screen. Please use the Zoom – functions at the left vertical tool bar (or use „Free hand symbols‟, see next page) to change the view. Select Append straight line to axis from the upper menu. The length of the straight line is 60.0 m. Confirm The axis is now defined in the “ground plan” and is displayed on the screen. Top level of GP with axis in plan © Bentley Systems Austria

  21. 21. RM Bridge Construction of Cross-Section Training Getting Started – GP – DIN 5-4 5.1 Definitions 5.1.1 Construction Lines Construction lines are defined with the available icons (see above) and are needed for the basic cross-section shape. Each construction line (CL) is defined relative to an existing line, thus all new construction lines are depended on CL1 and CL2. 5.1.2 Reference Points The intersection of CL1 and CL2 represents the axis of the bridge and acts as a reference point for the position of the cross-section in the overall 3D geometry. 5.1.3 Cross-Section The shape of the cross-section is defined by individual elements. These elements are based on the intersection points of the construction lines. These 2 dimensional elements are cre- ated with either 3 or with 4 corner nodes. A polygonal line around the element defines the border, the first and the last polygon part close the element. The order of input does not matter (cycle), the polygonal line must not cross itself. 5.1.4 Parts Cross-section elements with different properties can be written into a separate part. Com- posite cross-section for instance has 3 parts: one for the steel, one for the concrete, one for the composite cross-section. 5.1.5 Reference Sets In addition to the cross-section geometry information for the structural analysis such as temperature points, reinforcement layers, stress points and others are defined in so called reference sets. Properties (e.g. material) of a „Reference Set‟ can be defined and grouped in so called „Attribute Sets‟. 5.1.6 Layer Management Each object of the cross-section can exist in all, one or several graphical layers. © Bentley Systems Austria
  22. 22. RM Bridge Construction of Cross-Section Training Getting Started – GP – DIN 5-5 5.2 Definition of Construction Lines Six vertical and four horizontal lines are needed for the following cross-section.

Several seg- ments may exist for one project. Changing the currently active segment is done by click- ing the wanted segment and confirming with <OK>. © Bentley Systems Austria
  37. 37. RM Bridge Segment Definition Training Getting Started – GP – DIN 6-2 6.1 Definition of the Structural System The next step in GP is the assembly of the structural system. A structural system consists of Elements, Nodes, Cross-sections and Material properties. Each segment consists of several segment points. Each segment point is defined in 3D with its position along the axis. The structural nodes are created using these segment points, the structural elements are generated using the spacing between the segment points. Material properties are assigned to the elements, the cross-sections are assigned to the segment points. 6.2 Definition of Segment Points Open the segment point listing by clicking the symbol on the right side. The table will be empty since no data has bee n defined yet. Segment Point Listing Define new segment points by clicking the "Insert after" - button (at the left of the gen- eral screen). The structural system shall start at 0 and shall end at Station 60.0 m. All elements will have a length of 3.0m, 20 elements will finally compose the girder. 10 elements for the left span and 10 elements for the right span. © Bentley Systems Austria
  38. 38. RM Bridge Segment Definition Training Getting Started – GP – DIN 6-3 The input for the Seg- ment Points can be seen Insert Segment Points in the Figure on the left side.

(60m long with elements of 3 m length). Segment Points 6.3 Cross-Section Assignment The assigned cross-sections are shown in the segment list. The column „OK‟ describes if the cross-section at this stage is correctly defined for the further procedure. The „+‟ shows that at this station the appropriate cross-section is assigned. If this sign switches to „-„ the cross-section was recently modified after it had been assigned to the segment.. In the lower list all specified variables, parts and connections of the cross-section are displayed. Later on tables and formulas will be assigned to those variables. © Bentley Systems Austria
  39. 39. RM Bridge Segment Definition Training Getting Started – GP – DIN 6-4 6.4 Assignment of Element Numbers The element and node numbering for the whole system can be done at once. First se- lect “parts” to view the undefined parts. Only Element numbering one line is displayed since the cross-section exists only of one part. The element numbering should start at segment point 1, the first element and node-number should be “101”. At the end of the first element (101) the node–number is “102”. The in- crement is definition by “1”. The properties of the material is:C_35/45 (DIN 1045-1) will be applied. All elements are grouped with the name “MG“ (main girder).
