A horizontal flexural member (a girt) in the wall of a prefabricated metal building is composed of a C130 × 13 channel. The girt is to span 4 m between simple supports and is subjected to full-span uniformly distributed line loads as shown. The girt is oriented with the Y–Y (weak) axis in the horizontal plane. The gravity load is 400 N/m and includes the weight of the girt. The wind load is 600 N/m. Find the maximum tensile and compressive stresses.
