Influence of patch load length on strengthening effect in steel plate girders
Abstract
The present paper aims to numerically investigate the influence of patch load length related to various geometric parameters on the patch loading resistance of steel plate girders. Geometric parameters such as the web thickness, web panel width, and flange thickness are varied in combination with flat longitudinal stiffeners with varying rigidity in determining ultimate strength for various patch load lengths. Of primary interest in this paper is the strengthening effect, defined as the ratio between the ultimate strength of longitudinally stiffened and unstiffened steel plate girders.
