Allows you to check concrete tensile stress to determine if a given wall is a gravity wall or requires structural reinforcement. Retwall can be used to design a retaining wall for a given set of load inputs, or analyze an existing design. You can select the function of the wall (earth retaining or flood wall), and perform a stability analysis, calculate the bearing pressure, compute the overturning moment, find active and passive pressures, as well as provide a recommendation for rebar in the wall. The program can handle both US and SI (Metric) units, and lets you edit the code factors. In addition, RetWall includes a soil database editor, as well as a concrete property editor.
