I believe the backwall dead load is not being added to the load effects calculated in the analysis tab under Load Case DC which is used for design and footing stability checks. I found this issue in the LEAP Bridge Concrete V19 Substructure module. Later I checked the issue in the latest version of OpenBridge Designer V10.11.00.40 which includes LEAP Concrete Bridge V22.00.02.19 Substructure module and it still exists.
It would really help me out if you could provide some insight into this matter. Thank you.
I tested this issue in the current release version and the program is applying the back wall load and moment on the abutment.
In the loads TAB please select the DC load case and then Check the "include Backwall" option and click GENERATE.
The program applies the UDL and moment on the abutment.
It should work in your version and case as well.
Please let me know if this is the information you are looking for.
That answered my question. Thank you!
you are welcome
