Abstract
Tsunami debris attacked and destroyed many buildings in the 2011 off the Pacific coast of Tohuku Earthquake. Steel tubular members are popularly used for the beam-columns of buildings in Japan, so that an evaluation method of the resistant capacity of the member against Tsunami debris becomes the urgent problem. One of the difficulties to develop the evaluation method is that the local deformation caused by the collision object degrades the overall strength of a steel tubular member which degrading rate may be changed by the contact tip shape of the object. In order to investigate the effects, we conducted a static nonlinear analysis of steel tubular members subjected to concentrated lateral loads by using the finite element analysis (FEM) program MSC Marc. The accuracy of the FEM analysis model is verified by the experiment. Being based on the parametric numerical study, it is discussed the degrading effect of loading tip shapes on the lateral load-deflection relations and the collapse modes of steel tubular members.
