Steel Structure Optimization: Part 6B – Optimization using Tapered member-An Overview || Taper Depth

Have you ever wondered why in PEB industry, tapered sections are used as a rafter or column member? Is it only for economic design? Also, how these tapered profiles and section depths are calculated along the span?

If we design a steel structure in STAAD using traditional design approach, then we need to manually review the design results and change the section size so that the optimum section is used. This process is time consuming, also it is very hard to find out the most economic section by trial and error method.

Optimization does not mean use of an economic section only, rather we need to ensure proper distribution of material where it is required. And with this approach, we can further reduce the steel quantity and overall construction cost of any structure.

In this video, I will cover the basics of tapered member design, how the profiles are determined, how the section depth at various location is fixed. Also I will cover the factors which affect the section selection process including high shear, interaction and serviceability conditions.
