Specification Section: Retaining Walls – Models and Materials

Matt Ball on August 11, 2015 - in Retaining Wall

Retaining walls and soil-retention products continue to evolve, as does the software that designs these systems and simulates their performance. The following resource aims to serve those who design and model such structures as well as specify the materials and products for projects. The Models & Materials section is an ongoing focus at Informed Infrastructure.

MODELING/MEASUREMENT/SIMULATION

Allan Block offers a powerful and user-friendly retaining wall design software which is the most advanced in the industry that can optimize the design process thus saving time and increasing productivity. AB Walls Design Software is a comprehensive design tool which outputs professional quality construction drawings with technical support data. It allows designers to transfer a conceptual layout from a site plan to a complete wall solution and then export to various CADD software programs including ReSSA. In addition, designers can generate elevations, plans and multiple cross sectional views of their retaining wall projects.

MIDASoft Inc.’s GTS NX is a comprehensive 2-D/3-D geotechnical analysis software package equipped to handle the entire range of geotechnical design applications. GTS NX has effective options for dealing with structural or fiber reinforcements. For detailed analysis, structural elements (including some pretension) can be introduced in a construction-stage analysis so forces and moments in the structure can be computed along with the interaction between structure and ground.

Oasys Software’s Frew enables engineers to quickly define and solve even the most complex embedded retaining-wall design problems. Frew checks the stability of cantilever and propped retaining walls using the Limit Equilibrium analysis methodology. Using Soil Structure Interaction, Frew predicts the displacement, shear forces and bending moments of the wall. Engineers can calculate the required wall-embedment length using a choice of methods.

LOCK+LOAD Retaining Walls Ltd. said that the modular cantilever design of its walls allows for consistent compaction of backfill, so fences and barriers can be constructed adjacent to the wall face. The LOCK+LOAD modular design uses two high-strength, lightweight, fiber-reinforced concrete components assembled into a single, rigid cantilever unit. These units can be used alone to build short walls or in conjunction with soil reinforcement for tall retaining structures.
