The paper concerns the experimental results performed on steel (S 235) zinc plated panels
having 1500 x 1150 x 1.5 mm dimensions, linked to hinged steel frame. In order to the
slenderness of plates, considerable displacements out-of-plane are evident at loads
significantly lower of ultimate load. Considering the steel constitutive curves obtained from
tensile tests, the comparison of experimental and numerical (ADINA) results is proposed.
The results show the excellent seismic behaviour of the system having stable hysteresis loops
