Cantilever Retaining Walls: How to Calculate the Bearing Pressure

By: Javier Encinas, PE | July 25, 2017 A retaining wall is a structure exposed to lateral pressures from the retained soil plus any other surcharges and external loads. All overall stability failure modes must be thoroughly checked, including the bearing capacity of the supporting soil. This article discusses the calculation of the soil bearing bearing pressures under cantilever retaining walls. Our software ASDIP RETAIN will be used to support the discussion. What are the typical loads on a retaining wall? In addition to the retained backfill, retaining walls may be subject to surcharge loads at the top [...]

How to Design Restrained Retaining Walls Using ASDIP RETAIN

By: Javier Encinas, PE | May 22, 2017 ASDIP RETAIN is a structural engineering software for design of retaining walls. ASDIP RETAIN software includes the design of either concrete or masonry top-restrained retaining walls based on the latest ACI 318 and MSJC provisions. Following is an overview of the steps required to design basement retaining walls using ASDIP RETAIN. Click To Enlarge Select the stem material, either concrete or masonry. ASDIP RETAIN will adjust the input fields. Enter the wall and footing dimensions in the Geometry tab. Wall can be modeled as either pinned or [...]

How to Design a Fence Wall Using ASDIP RETAIN

By: Javier Encinas, PE | May 2, 2017 ASDIP RETAIN is a structural engineering software to design retaining walls. However, the software is so flexible that it can also be used to design a masonry fence wall exposed to wind. This article shows the steps required to design a fence wall using ASDIP RETAIN. Click To Enlarge As an example, let's design a typical fence 7'-0" high exposed to a wind load of 20 psf. The first obvious step in the software is to set the backfill height to match the soil cover at [...]

Cantilever Retaining Walls: How to Calculate the Sliding Safety Factor

By: Javier Encinas, PE | March 13, 2017 Retaining walls are structures designed to bound soils between two different elevations, therefore they are mainly exposed to lateral pressures from the retained soil plus any other surcharge. Cantilever walls may be sensitive to sliding problems, particularly if founded on poor soils. This article discusses the sliding calculations in either concrete or masonry cantilever retaining walls. Our software ASDIP RETAIN will be used to support the discussion. What are the pressures acting on a retaining wall? In addition to the retained backfill, retaining walls may be subject to surcharge loads at [...]

Cantilever Retaining Walls: How to Calculate the Overturning Safety Factor

By: Javier Encinas, PE | January 15, 2017 A retaining wall is a structure exposed to lateral pressures from the retained soil plus any other surcharges and external loads. All overall stability failure modes must be thoroughly checked, but cantilever walls may be particularly sensitive to overturning problems. This article discusses the overturning calculations in either concrete or masonry cantilever retaining walls. Our software ASDIP RETAIN will be used to support the discussion. A typical retaining wall is composed of four main components: the Stem, the Toe at the front of the wall, the Heel at the backfill side, and [...]

Restrained Retaining Walls: A Design Overview

By: Javier Encinas, PE | November 30, 2016 Retaining walls are structures designed to bound soils between two different elevations. A retaining wall is then mainly exposed to lateral pressures from the retained soil plus any other surcharge. Many retaining walls are cantilever-type, but it's also common to find in practice walls that are laterally restrained at the top, such as in the case of basement walls supported laterally by an elevated floor slab. This article discusses the design of either concrete or masonry top restrained retaining walls. Our software ASDIP RETAIN will be used to support our discussion. A [...]

Cantilever Retaining Walls: An Overview of the Design Process (Part 2)

By: Javier Encinas, PE | February 21, 2016 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 [...]
