The software is based on a standard analytical approach, which follows AS 4678 - 2002, AS3600-2009 and AS3700-2011 for stability assessment, and design of the concrete base and the masonry.
R-WALL software provides a simple user interface, which allows the user to choose from one of the four pre-defined retaining wall types, and specify the design parameters. Once, all input data are entered, the user can perform analytical check for the stability and strength. The stability check includes overturning, sliding and load bearing failure of the base. The strength includes check of the stem and the concrete base.
The design follows the ultimate limit state principle. It takes into consideration the following ultimate limit state modes:
