The behavior of laterally restrained thin-walled Z-section beams subjected to uplift load was analyzed by means of the model composed of steel thin-walled Z-section beams 200/60/15/2 laterally restrained by trapezoidal steel sheeting T 53/162,5/1, Figure 1. The rotation and lateral displacement at beam supports is not possible. The calculation model for the thin-walled beam laterally restrained by trapezoidal steel sheeting is presented in Figure 2.
