Failures and Prediction Methods of Lateral Buckling Strength of H-Shaped Beams Connected by Flush End Plates

Abstract

In this paper, the experiment of the full scale specimen and the nonlinear FEM analysis have been conducted to obtain the behavior of H-shaped beam connected by the flush end plates which fall into the connection failures or the lateral buckling. As a result, the intensities of restraint of the beam ends are reduced by the end plates deformation, and then the lateral buckling strengths of the beams are reduced by the deformation. We present the prediction methods of the lateral buckling strength of the beam influenced by the out of plane deformation of the flush end plates.
