型钢尺寸对SRC节点承载力的影响

摘要

The specially-shaped column structures have been widely used in practice of occupant buildings in China recently. The shearing resistance of joint between the column and beam of the specially-shaped column structures is insufficient, however, some measures such as using steel in the specially shaped column appeared in recent decades. This thesis deals mostly with the size of the steel in the specially shaped column so that getting the most suitable size. The thesis use nonlinear finite element software ABAQUS analyze the joints of specially-shaped column with shape of T of joining the different size steel , then obtain the most suitable size for steel.%目前,异形柱结构在我国住宅中得到了广泛的应用.虽然异形柱结构的节点抗剪承载力较为薄弱,但是近年来已经出现了加入型钢等提高异形柱节点抗剪承载力的措施.本文主要就异形柱节点中加入的型钢进行研究,期望得到型钢的一个理想尺寸.文章利用有限元分析软件ABAQUS对加入不同尺寸型钢的T形异形柱节点进行分析,得出了较为合适的型钢尺寸.
