I want to apply a lateral soil load to a structure below grade in STAAD. I modeled the retaining wall as a plate. How do I go about doing this?
Use plate pressure Hydrostatic
Hydrostatic loading is the best option here to apply the lateral earth pressure. You will get the details in help file below location.Home > Modeling > M. Loading Your Model > M. Load Items > M. To add a hydrostatic load to objectsPlease try to orient the plates in same pattern so that loads can be generated automatically without any issue.
