The FStr computer application gives to the user an easy and an intuitive elastic buckling analysis, through a Finite Strip Method, and its modal visualization of a thin-walled structural element. Besides the modes, the user can determine the critical buckling load in each critical length.FStr Computer Application is a software developed on the basis of the Finite Strip Method formulation.The formulation uses trigonometric functions in longitudinal direction in series, with the purpose of interpolate the solution inside the strip, and form a shape suitable to any type of end boundary condition.Signature curves are one type of analyse the results, through a set of longitudinal lengths. Then, the user can analyse the critical modes in any critical length.3D buckling modes, with colorful plots, helps the user to identify the critical buckling mode easily.
