In this guide, we will explore how to find the necessary design properties for a Purlin beam-column, specifically focusing on DIY Problem #2 with centerline dimensions of h = 7.507 in, b = 1.889 in, d = 0.795 in, r = 0.217 in, and t = 0.059 in. We will also consider material properties with E = 29500 ksi, n = 0.3, G = 11346 ksi, and fy = 55 ksi. Additionally, we will analyze the applied loads, with a P = 1 kips and M = 30 kip-in, to determine if the DIY section is adequate to meet the ASD demands.
