Retaining Wall on Piles Design Example Using ASDIP RETAIN

Insert Image By: Javier Encinas, PE | July 4, 2018 ASDIP RETAIN is a structural engineering software for the design of retaining walls. It includes the design of cantilever retaining walls supported on piles based on the IBC / ACI 318 provisions. This document is a step-by-step design example of a typical retaining wall on piles using ASDIP RETAIN. As an example, consider the retaining wall shown below, which is part of an access ramp in a parking garage building. Due to the poor soil conditions, the soils report has recommended the use of steel piles HP12x53, with the shown [...]

Retaining Walls Supported on Piles: A Design Overview

By: Javier Encinas, PE | May 22, 2018 A retaining wall is a structure exposed to lateral pressures from the retained soil plus any other surcharges and external loads. When the wall is founded on soil, all overall stability failure modes need to be checked. But what about when the wall is supported on piles? This article discusses the design steps in the design of retaining walls supported on piles. Our software ASDIP RETAIN will be used to support the discussion. What are the loads transferred to the foundation? In addition to the retained backfill, [...]

How to Design Counterfort Retaining Walls Using ASDIP RETAIN

By: Javier Encinas, PE | April 3, 2018 ASDIP RETAIN is a structural engineering software for design of retaining walls. It includes the design of counterfort retaining walls based on the latest ACI provisions. Following is a graphical overview of the required design steps, with annotated screenshots of the software. Click To Enlarge Enter the dimensions of the stem, counterforts, footing, and shear key in the Geometry tab. Specify the backfill height and slope angle. ASDIP RETAIN shows a tab for each element. Three ways to show results: At-a-Glance, Condensed, and [...]

ASDIP RETAIN 4 Is Coming Soon: A Brief Overview

By: Javier Encinas, PE | March 8, 2018 ASDIP RETAIN is a structural engineering software for design of retaining walls. The new version 4 of this software will be release shortly. This document is a brief overview of some of the most important new features included in ASDIP RETAIN 4. Retaining walls supported on piles Now ASDIP RETAIN 4 includes the design of retaining walls supported on piles. The piles information can be entered seamlessly, such as pile type and spacing, pile capacity, batter angle, etc. And you can switch between piles and no-piles [...]

Basement Wall Design Example Using ASDIP RETAIN

By: Javier Encinas, PE | February 21, 2018 ASDIP RETAIN is a structural engineering software for design of retaining walls. ASDIP RETAIN includes the design of top-restrained retaining walls, also called basement walls, based on the latest ACI 318 provisions. The design of retaining walls may become time-consuming, since the calculations involve multiple load types and combinations, fixity conditions, and the application of the Code provisions to design the reinforcement. This document is a step-by-step design example of a typical concrete basement wall using ASDIP RETAIN. Example As an example, let's consider [...]

Cantilever Retaining Wall Design Example Using ASDIP RETAIN

By: Javier Encinas, PE | February 6, 2018 ASDIP RETAIN is a structural engineering software for design of retaining walls. ASDIP RETAIN includes the design of concrete cantilever retaining walls based on the latest ACI 318 provisions. The design of retaining walls may become cumbersome and time-consuming, since it involves an iterative process to calculate the stability ratios, and the application of the Code provisions to design the reinforcement. This document is a step-by-step overview of a design example of a typical concrete cantilever retaining wall using ASDIP RETAIN. As an example, let's consider a cantilever retaining [...]

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 [...]

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 [...]
