ULS-RWS software Overview

What is ULS-RWS?

A software that deals with the ultimate limit state (ULS) analysis for all types of embedded retaining wall (cantilevered, single-propped and multi-propped).
The main focus is to derive the wall embedment (penetration), complying with various Standards and Codes. The bending moment/shear force diagrams and support force for cantilevered and single-propped cases also provide significant insight combined with proper engineering judgement.

Definition

Relatively thin walls
Equilibrium is achieved from the lower embedded depth of wall and the props if any
The bending capacity of such walls plays a significant role in the support of the retained material

Wall Support Types

Cantilevered
Single propped
Multi-propped

Design Procedure

A set of calculations (ULS) to determine the minimum embedment necessary to achieve equilibrium for the ultimate limit states, which is the purpose of this software development.

A set of soil-structure interaction (SSI)analyses to determine the relevant action effects in the retaining structure (e.g. bending moment, shear force and strut/prop force) which will subsequently be provided for structural design calculation, and wall displacements which will be used for serviceability limit state (SLS) assessment
