How to Use the Pre-combined Load Feature in ASDIP Software

By: Javier Encinas, PE | May 16, 2017 ASDIP is a structural engineering software for the design of structural members based on the ASCE 7 load combinations. But what about if you don't want your loads to be internally combined? This blog post discusses this important feature in ASDIP software. Structural engineering is all about calculations with loads, which are classified in different types, called Load Cases, such as Dead, Live, Snow, Wind, Seismic, etc. Typically the calculation results are generated and stored individually per each load case. These load case results are then affected by load factors in order [...]

Can Anchor Rods Resist High Shear Loads?

By: Javier Encinas, PE | April 26, 2017 During a recent technical support session a customer asked how effective the anchor rods are, as compared to shear lugs, to resist high shear loads. The obvious answer was that shear lugs are by far more effective. Rather than arguing with theories, I decided to quantify the answer by testing, using our software ASDIP STEEL. This document reports my findings. For this experiment, I selected a 18"x 18" base plate supported on a 24"x 24" pedestal, which are very common sizes. The column will transfer the factored loads shown below [...]

Shear Lug Design: Overview of the ACI Provisions

By: Javier Encinas, PE | April 4, 2017 Shear lugs are steel elements welded to the underside of base plates to resist shear loads. The design of shear lugs is covered by the ACI 349 anchorage provisions. This post is an overview of the structural design process. Our software ASDIP STEEL will be used to support our discussion. How do you calculate the shear force in a shear lug? The lateral forces acting on a structure will produce a horizontal reaction at the foundation level. For steel frames supported on base plates, a small horizontal force can be resisted by the [...]

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 [...]

How to Design Shear Connections Using ASDIP STEEL

By: Javier Encinas, PE | February 13, 2017 ASDIP STEEL is a structural engineering software for design of steel members and connections. ASDIP STEEL software includes the design of shear connections based on the AISC 360 provisions. Following is a graphical overview of the required design steps, with annotated screenshots of the software. Click To Enlarge Select the connection type: single or double angle, single plate, or tee. Support can be either column flange or web, and beam web. Select support and beam sections from the AISC built-in database. If beam is [...]

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 [...]
