Evaluation of maximum strength and cyclic deterioration behavior of shear-yield-precedence beam

—Bending-Shear Behavior of shear-yield-precedence short-span beam—

Abstract

In our previous study, shear-bending loading tests were carried out in order to estimate the bending-shear behavior of shear-yield-precedence short-span beams. The results demonstrated that the short-span beams have good structural behavior. This paper describes simulation analyses of representative specimens using FEM. A method for evaluating maximum shear strength is proposed and verified using test and analytical results. The method takes into account the diagonal tension field. When the width-thickness ratio and the shape ratio of the beam web are appropriately designed, the short-span beam is proved to have sufficient deformation capacity.
