In recent years, we have witnessed a considerable increase in the study of thin flat sheet and various issues related to it. However, comprehensive studies on the formulation of curved plates are rare. Due to the growing use of curved panels in various fields, in this study, the effects of torsional stiffness, bending stiffness and axial stiffness of the peripheral members on shear buckling andpost buckling behavior of curved steel panels were investigated. To do this, ABAQUS software and Riks method were used. The findings revealed thatflexural stiffness and axial stiffness do not increase buckling resistance of panels while the torsional stiffness on elastic buckling resistance of panels was found to be effective. The nonlinear behavior of panels is the function of stiffness ratio of peripheral members to stiffness of panels. Stiffness of peripheral members on capacity after buckling anddevelopment of principal stresses of panels were not affected.
