MODELING AND SIMULATION OF PERFORMANCE OF STIFFENED PLATES DURING STRENGTH ANALYSIS

摘要

This paper performs strength analysis on arbitrarily stiffened and regular stiffened plates to investigate the strengthening effects of stiffener's height, number, and arrangement on the stiffened plates' ultimate strength limit (USL). It is also found that the strengthening effects of an arbitrarily oriented stiffener (or oblique stiffener) can be decoupled to two perpendicular regular stiffeners which are located in appropriate positions. Nonlinear buckling analyses were performed on the arbitrarily stiffened plates with one and two arbitrarily oriented stiffeners to verify this finding. The outcome of this paper can be further extended and applied to develop simplified semi-analytical models for buckling strength analysis of constructional plates.
