Analyzing a Beam Supporting a Concrete Slab and Subjected to Dead and Live Loads per LRFD and ASD

June 8, 2017 Abdul Siraj, P.E.

In this post, I will discuss the third example in our steel design course covering the analysis and design of beam members. The goal of this steel design example is to analyze a beam supporting a concrete slab and subjected to dead and live loads per LRFD and ASD. We are using the 13th edition of the AISC Steel Construction Manual.


The problem statement states,


A W16 x 57 of A992 steel is 32′ feet long and supports a reinforced concrete floor slab. The service dead load is 500 lb/ft (weight of beam not included) and the service live load is 600 lb/ft. Check if this beam is adequate per LRFD and ASD.
