Earth Pressure [SIG]

Earth-pressure loads in OpenBrIM model the horizontal pressure exerted by retained soil or a live-load surcharge on abutment back walls and the footings they rest on. The Abutment Earth Pressure library object converts an active earth-pressure coefficient and backfill unit weight into a triangular (earth pressure) or uniform (live-load surcharge) surface load that is applied to the selected abutment at a chosen construction stage.

For a detailed explanation of each library object, refer to the relevant section of the documentation.
