Hello,
I am working in the substructure module of Bridge Concrete and I am seeing something that does not quite make sense to me, however I may be missing something.
Under the loads tab, I added a braking force and did the auto-generate function with the proper number of lanes.
Based on some quick hand calcs, it appears the loads were applied under the Bearing/Girder section correctly. However, after the analysis is run, viewing the data for Type: Load Case, Item: BR1, all of the forces and moments are zero.
Also, why does the software require that the number of braking loads have to match the number of live loads? Is there a way to not require this?
Thanks
1) While generating Live Load , it is not required to Check the "Braking Load cases" option as it will generate too may BR load cases and ultimately the number of Load combination will increase which will affect the analysis.
2) Only one BR load case is enough.
3) Make sure the BR and LL load cases is made to NONE in the Load combination window.
Please see the attached screenshots for more information.
