ASDIP RETAIN is structural engineering software for design of retaining walls. Competent design of retaining walls can maximize land use and substantially increase property value.
This is a two-part blog post. In part one, Javier reviewed the basics of earth lateral pressure theories and overall stability checking. This second part of the article covers the typical loads in a retaining wall, and the structural design of the different components.
What loads act on a retaining wall?
Ordinarily, retaining walls are subject to surcharge loads at the top of retained mass. A surcharge may be a strip load. A strip load describes a distributed load within a limited width. The pressure distribution is calculated using the Boussinesq approach. The stem may also have concentrated loads at the top.
When the stem extends above backfill the retaining wall may be exposed to wind load. When retaining walls are located in seismic zones the seismic effects are considered by utilizing Mononobe-Okabe approach. ASDIP RETAIN is structural engineering software for engineering professionals to quickly model retaining wall loads. The image below depicts external loads of retaining wall.
