Tapered steel plates are classified into 2 categories by the difference of directions of applied force and thickness change; Longitudinally profiled steel plates and transversely profiled steel plates. It is confirmed that the former can be applied to steel bridges and make it possible to reduce the construction cost and improve sstmctutal rationality. The latter is also studied and it is shown that it is also effective for improving strength and ductility in case of the square plate by parametric numerical approach Proposed herein is the evaluation of ultimate strength of both tapered steel plates considering various boundary conditions, longitudinally and transversely profiled steel plate and its validity has been discussed.
