Performs
analysis and design of reinforced concrete cantilevered and restrained
retaining wall systems. The retaining wall system consists of a wall
stem of constant or variable thickness, a base (toe and heel) and
an optional key. Backfill (level or sloping) and optional frontfill
soil with same or different properties and water elevation may be
specified. Full and partial surcharge loads and top-of-wall loads
may be applied.
In the Check mode, for a known system dimensions and applied
loading, the program computes the pressure profiles, and checks for
stability, designs for flexure, and checks for one-way shear.
In the Design mode, the program selects the size of the base
(heel and toe) and wall thickness so that the system can safely and
adequately carry the applied loads. |
