How to design cold-formed steel beams and columns to American Standards Using AISI S100-16

About this event

With the increasing price of wood material in construction, cold-formed steel framing is rapidly becoming the material of choice in sustainable construction due to its properties being lightweight, extremely strong, non-combustible, and relatively easy to install.

Designing CFS can be challenging/CFS is unique in its design due to several issues like buckling. Due to its low thickness to width ratio, CFS members can easily buckle when compressive, bearing and shear bending forces are applied. Therefore, buckling is a major design consideration for CFS.

Join us on Wednesday, September 28th, from 1 pm to 2 pm Eastern Time (ET) to learn how you can design cold-formed steel beam and column to American Standards AISI S100-16.

Normally, to produce a compliance design, many engineers need to either use overconservative span tables or figure out the incredibly complex CFS engineering standards. ClearCalcs makes figuring out the standard easy with our integration of the Direct Strength Method in CFS design calculations.

In this webinar, we will cover:

• General overview of AISI S100-16 and how it relates to cold-formed steel beam and column design
• Common real-world examples and applications using cold-formed steel
• Worked examples in ClearCalcs
• Common limitations and assumptions in ClearCalcs’ CFS Beam and Column calculator
• Highlight on the newly released Back-to-Back and Boxed Sections and how it can help your design workflow.

Webinar Summary

The webinar on Cold-Formed Steel Design to American Standards was hosted by ClearCalcs' Director of Customer Success, Connor Conzelman, and presented by Behnam Ordoubadi, Structural Engineering Developer. The webinar covered designing a cold-formed steel beam using AISI S100-16 and the direct strength method, with a focus on prequalified sections and strong access. The presentation materials will be shared for reference.

The current segment discusses the unique advantages and challenges of using CFS in construction, including its light weight, good strength-to-weight ratio, and susceptibility to buckling and web crippling. The section also highlights the need for careful design considerations and analysis to ensure structural integrity.

The segment goes on to discuss the preferred method for analyzing cold-formed steel beams, which is the finance strip analysis. The speaker emphasizes the customizability of CFS and provides an overview of the different capacities that need to be checked during the design process, including flexural capacity, shear capacity, load interaction, and deflection. The segment also delves into the details of global buckling and localized buckling, and how they affect the design of CFS beams.

The segment explains how finance strip analysis is used to analyze cold-formed steel beams, and highlights the importance of checking different capacities during the design process. The speaker also discusses the specific challenges of global and localized buckling, and provides equations for calculating critical buckling capacities. Additionally, the segment covers the design considerations and equations for analyzing shear population and web crippling in cold-formed steel beams.
