Steel / Composite Beams: Optimizing the Design with ASDIP STEEL

By: Javier Encinas, PE | March 27, 2017 Beams are structural elements that support loads applied transversely, which produce a combination of shear and bending stresses. The structural design of steel beams includes the check of multiple limit states for both shear and bending. For composite beams, it’s important to consider the loads that will be applied before and after the composite action takes place. In the pre-composite stage, the flexural behavior of a steel beam is a function of the unbraced length Lb for the limit state of lateral-torsional buckling. In a composite beam, shear connectors are usually provided to transfer [...]

Shear Connections: Overview of the Design Process

By: Javier Encinas, PE | January 24, 2017 Shear connections are typically used to connect beams to other beams or columns. Such connections transfer shear, with minimum rotational restraint, as opposed to moment connections. This article is an overview of the AISC provisions for the design of shear connections. Our software ASDIP STEEL will be used to support the discussion. What are the components of a shear connection? A typical shear connection is composed of three parts: support, connector, and beam. The support may be another beam or girder, a column flange, or a column web. The connector may [...]

Anchor Rod Design: Overview of the ACI Seismic Provisions

By: Javier Encinas, PE | January 9, 2017 The seismic design of anchor rods is included in the ACI 318 code, originally in the Appendix D of the ACI 318-11 and earlier, and now in the Chapter 17 of the ACI 318-14. This document is an overview of the ACI 318 seismic provisions that affect the design of anchor rods. The anchor rods are usually subjected to a combination of tension and shear forces. The ACI treats separately tension and shear, and then it combines both effects in an interaction diagram. The seismic provisions apply to anchors in structures assigned to [...]

Anchor Rod Design – The Complex ACI Provisions (Part 2)

By: Javier Encinas | November 7, 2016 The design of anchor rods has become more complex with the development of the ACI 318 anchorage provisions. This is the second part of our post regarding the design of anchor rods. In the first part we covered the ACI provisions for the design of anchor rods in tension. Now we will cover the design of anchor rods in shear, as well as the tension-shear interaction. Our software ASDIP Steel will be used to support our discussion. How do you calculate the shear in anchor rods? The lateral forces acting on a structure [...]

Anchor Rod Design – The Complex ACI Provisions (Part 1)

By: Javier Encinas | October 2, 2016 The design of anchor rods has become complex and cumbersome with the development of the ACI 318 provisions, originally in the Appendix D of the ACI 318-11 and earlier, and now in the Chapter 17 of the ACI 318-14. This document covers the required steps in the process of the design of the cast-in anchor rods normally encountered in column base plates. The anchor rods are usually subjected to a combination of tension and shear forces. The ACI treats separately tension and shear, and then it combines both effects in an interaction diagram. [...]

Steel and Composite Beams: A Design Overview

By: Javier Encinas, PE | June 20, 2016 ASDIP STEEL includes the design of steel and composite beams. This structural engineering software is based on the latest AISC 360 provisions. This article provides an engineering background overview of the structural design of steel and composite beams. Beams are structural elements that support loads applied transversely, which produce a combination of shear and bending stresses. Composite action is developed when two load-carrying structural elements, such as a concrete floor slab and its supporting steel beams, are integrally connected and deflect as a single unit, substantially increasing its strength and stiffness. A [...]

ASDIP Project Manager – The Core of the Software

By: Javier Encinas, PE | March 28, 2016 ASDIP is structural engineering software for member design. When ASDIP opens, a window pops up showing a menu bar and icons at the top, some buttons at the left, a tree at the right, and more buttons below the tree. This is the ASDIP Project Manager, as shown in the picture below. This blog post covers the purpose and capabilities of this part of ASDIP software. What is the purpose of the Project Manager? In ASDIP software all project information, including calculations, settings, preferences, etc, is stored in a [...]

ASDIP STEEL: Base Plate and Anchor Rod Design

By: Javier Encinas, PE | January 30, 2016 ASDIP STEEL includes the design of base plates as well as the anchorage system. This blog post covers the principal design steps. This structural engineering software is based on the AISC Design Guides # 1, Blodgett "Design of Welded Structures", and the ACI 318-11 Appendix D. Base plates are structural elements at the bottom of columns to spread the concentrated load over a larger supporting area, so that the bearing stresses are under the acceptable limits. Depending on the type of frame the column belongs to, the base plate may be subject to compression, [...]
