抄録

A series of elastoplastic large deflection analyses are performed on stiffened plates with flat-bar and angle-bar stiffeners subjected to thrust, and the influences of sectional geometries of stiffeners on the buckling/plastic collapse behaviours are investigated. It has been found that: (1) Local panel buckling strength among stiffeners, post-buckling inplane rigidity and ultimate strength is increased owing to the stiffener; (2) stiffened plates undergo elastoplastic secondary buckling after local panel buckling; (3) higher ultimate strength is attained by stiffeners with lower depth-to-thickness ratio of a web, but, the reduction in capacity after the ultimate strength is more rapid for stiffened plates with such stiffeners; (4) when stiffeners with relatively high depth-to-thickness ratio are provided, the ultimate strength is lower than with a lower depth-to-thickness ratio, but the capacity reduction after the ultimate strength is rather moderate.
