Project Setup and Section Upstand
The first steps in creating the structural model can now be taken by defining the design Sections to be used and setting up the flat slab 30m long by 4m wide. There will be 20 equally spaced elements longitudinally and 6 elements transversely, with the edge element 0.5m and the internal element 0.75m.
Begin a new project using the main menu File | New | Create From Template and selecting “EU Project” from the options.
In the Titles form add a Project Title of “Composite Banana Bridge” with a subtitle “EU Example 10.2” and Job Number: “10.2”.
Add your initials in the Calculations by: field.
In the Materials navigation window delete all the materials using the Clear All task as the required materials will be defined when the beam file is imported.
In the Design Beam navigation window toolbar click on
to add an “Existing Design Beam” and select the beam file “EU Example 10_2 Banana_beam.sam”. Then click the
icon on the toolbar to embed the beam (also creating the project materials).
In the Design Sections navigation window click on the
button, select New Section | Parametric Shape and add a rectangular parametric shape, 200mm wide by 250mm deep.
Set the Hook Point Reference to 1 with coordinates Y “0” and Z “100” (to give it the correct elevation with respect to the slab centre).
Set the property to the C32/40 concrete material before closing the form with ✓ OK.
Rename this Design Section to “Edge Upstand” using the right mouse button in the navigation window.
It is also necessary to define a Design Section for the “H” shaped piles, again using a parametric shape.
Click on the
toolbar button to select New Section | Parametric Shape.
Set Shape Reference to H and enter a width and height of 450mm.
Enter a thickness of 28mm for both horizontal and vertical and change Property to “S355/345”.
The Hook Point Reference should be set to “0” with Y and Z Coordinates of “0” and “0”.
Close the form with ✓ OK and then rename the section in the navigation window to “H Piles”. Save the file as “My EU Example 10_2 Sections.sst”.
