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 fullspan 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.
