How to create LUSAS model automatically?
ICDAS ARB 2019.00R is including Concrete Bridges (COB). Refer ICDAS COB for how to create LUSAS model automatically. In Excel BRIDGE sheet set parameter Bridge (=1) for Arch Bridge Revit and Lusas models, (11) LusasASB.cmd only.
There are two automations in FEM model for Arch Bridge: § Automatic creation of bridge geometry and FEM § Automatic creation of loads and combinations of loads on bridge Automatic creation of bridge geometry and FEM The bridge geometry in Lusas is the one you have created in Revit. It happens when you import LusasARB.cmd in Lusas, where LusasARB.cmd is automatically created when you run add-ins in Revit. Further, all of cross sections of bridge elements are also automatically created and assign to the bridge as fictive cross sections. From Geometric folder in Lusas you can select and modify cross sections which are visible on Bridge as the selected dark black elements. Full text description for geometric cross sectional attributes are listing below. 1. Longitudinal steel beam at the bottom 2. Transverse steel beam at the bottom 3. Diagonal steel beam at the bottom 4. Vertical beam to structural railing 5. Longitudinal steel beam railing 6. Diagonal steel beam to stiffen the railing 7. Arch tangent bottom leg 8. Arch curved elements in ellipse shape 9. Arch cross beam between the two arch 10. Hanger 11. Track1 concrete surface left side of STLo 11. Track4 concrete surface left side of STLo 15. Track5 concrete surface right side of STLo 18. Track8 concrete surface right side of STLo |
