Steel and Composite Beam Design Overview

By: Javier Encinas, PE | November 26, 2019ASDIP STEEL includes the design of steel non-composite or composite beams. This structural engineering software is based on the latest AISC 360 provisions. This article provides an engineering background overview of steel and composite beam structural design.Beams are structural elements that support loads applied transversely, which produce a combination of shear and bending stresses. Steel beams can be designed as non-composite or as composite beams. If non-composite, the loads are resisted by the steel beam alone.Composite action is developed when two load-carrying structural elements, such as a concrete floor slab and its supporting [...]

Cantilever Retaining Walls: Overview of the Design Process

By: Javier Encinas, PE | November 6, 2019 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. Competent design of retaining walls can maximize land use and substantially increase property value. This article discusses the required steps in the design of either concrete or masonry un-piled cantilever retaining walls. Our software ASDIP RETAIN will be used to support the discussion. A typical retaining wall has four main components: the Stem is the vertical member holding the backfill, the Toe is the portion [...]

Continuous Concrete Beam Design: A Structural Challenge

By: Javier Encinas, PE | October 23, 2019ASDIP CONCRETE is a structural engineering software for design of concrete members. It includes the design of multi-span continuous beams based on the latest ACI 318 provisions. This article discusses the steps in the structural design of concrete continuous beams subject to concentrated and distributed loads.What is a continuous concrete beam?Beams are structural elements that support loads applied transversely to the beam axis, which produce a combination of shear and bending stresses. Concrete beams are usually continuous, this is, they span between multiple supports acting structurally as a single element. This is possible [...]

Spread Footings Under Biaxial Bending: A Complex Design

By: Javier Encinas, PE | October 9, 2019 ASDIP FOUNDATION is a structural engineering software for footing design. It includes the design of concrete spread footings based on the latest ACI 318 provisions. This article discusses the complexities inherent to the design of spread footings when subjected to a combination of vertical and horizontal loads, and biaxial bending. For a simple spread footing with a vertical concentric compression load, the resulting bearing pressure is uniform and the shear and bending can be calculated easily by hand. If the column is at the corner of a building, then biaxial moments could [...]

Eccentric Combined Footing Example Using ASDIP FOUNDATION

By: Javier Encinas, PE | October 1, 2019ASDIP FOUNDATION is a structural engineering software for the design of concrete footings. It includes the design of combined footings, based on the ACI 318 provisions. This document is a step-by-step design example of an eccentric combined footing using ASDIP FOUNDATION software.Combined footing exampleAs an example, consider the combined footing shown below, which is part of the foundation of an industrial building. The left column is very close to the property line and it has a relatively light load compared to the adjacent interior column. Design the size, thickness and reinforcement of a [...]

Retaining Walls: Are You Calculating the Passive Pressure Correctly?

By: Javier Encinas, PE | Sept 23, 2019 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. In addition to the friction at the base, most retaining walls rely on the passive pressure at the front of the wall to prevent sliding problems. This article discusses the factors that may affect the calculation of the passive pressure in a retaining wall design. Our software ASDIP RETAIN will be used to support the discussion. What exactly is the passive pressure? When the [...]

Cantilever Retaining Walls: How to Calculate the Sliding Safety Factor

By: Javier Encinas, PE | Sept 10, 2019 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 how to calculate the sliding safety factor in 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 the [...]

Custom Load Combinations in ASDIP CONCRETE

By: Javier Encinas, PE | August 27, 2019 The applied loads in a structure are usually categorized according to the nature of the loads, called load cases, such as dead, live, snow, wind, etc. These load cases are then affected by some load factors in order to be combined between them and finally get a combined load. Load combinations are a very important part in the design process. This document shows how to specify the load combinations, and particularly the user-defined custom load combinations, in ASDIP CONCRETE. How do you specify the standard load combinations? Most design standards, such as [...]

What Systems of Units Are Available in ASDIP Software?

By: Javier Encinas, PE | August 14, 2019 ASDIP is a structural engineering software for design of building members and components. It includes the design of beams, columns, bearing walls, footings, base plates, retaining walls, etc. With this diversity of design modules in compliance with different design codes, it's important to consider the capability of the software to perform calculations using different systems of units. It's not uncommon nowadays to see a project being developed simultaneously in several countries. This document discusses in greater detail the options available in ASDIP software to work with different unit systems. What are the [...]
