In this post, I will discuss the fifth 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 non-compact beam undergoing elastic lateral torsional buckling per LRFD and ASD. We are using the 13th edition of the AISC Steel Construction Manual.
The problem statement states,
A W14 x 99 simply supported beam with a span length of 50′ is laterally supported at its ends and experiences the following loads:
DL = 500 lbs/ft
LL = 1000 lbs/ft
Fy = 50 ksi
Is the beam adequate for the given conditions per LRFD and ASD.
