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 [...]

Continuous Beam Design Example Using ASDIP CONCRETE

By: Javier Encinas, PE | October 17, 2017 ASDIP CONCRETE is a structural engineering software for design of concrete members. ASDIP CONCRETE includes the design of multi-span continuous beams based on the latest ACI 318 provisions. The design of continuous beams may become cumbersome and time-consuming, since it involves the analysis of the beam to find the moments and shears, 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 continuous beam using ASDIP CONCRETE. As an example, let's consider a continuous beam, [...]

Footing Design: How to Check the Shear Capacity per ACI 318

By: Javier Encinas, PE | August 14, 2017 The foundation is that part of the structure that transfers the loads to the supporting soil in such a way that the resulting bearing pressures are kept under acceptable limits. If the underlying soil is satisfactory, then a spread footing is usually the recommended solution by the soils engineer. In addition to the stability checks and the design for flexure, a spread footing needs to be designed for shear. This blog post discusses the shear checks required by ACI 318. Our software ASDIP FOUNDATION will be used to support our discussion. What [...]

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 Spread Footings Using ASDIP FOUNDATION

By: Javier Encinas, PE | July 12, 2017 ASDIP FOUNDATION is a structural engineering software for design of concrete footings. It includes the design of spread footings 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 footing dimensions in plan and elevation view. Specify the soil cover and the water table depth. Click on the Column tab and specify the column dimensions. The column can be offset in both directions. If column is a short pedestal, loads [...]

Combined Footings: How to Calculate the Bearing Pressures

By: Javier Encinas, PE | June 27, 2017 ASDIP FOUNDATION includes the design of concrete combined footings. This structural engineering software is based on the latest ACI 318 provisions. This post explains the calculation of the soil bearing pressures in a typical combined footing. A combined footing usually supports two columns. The use of a combined footing may be justifiable under conditions where the distance between columns is short, so a large excavation is not required. There are two common scenarios in practice: A property line exists at or near the edge of an exterior column, so a normal isolated footing [...]
