钢结构梁腹板开圆孔组合节点性能数值分析
Numerical analysis of the behavior of composite connection with opening in the beam web in steel structure
摘要
Abstract
In order to examine the composite action of the concrete slabs on the behavior of the beam-to-column composite joints with opening in the beam web, the ABAQUS software has been selected to build a finite element model of the joints. The numerical analysis taking account of the change of joint size and weakening parameters, shows the composite action of concrete slabs increased the strength and stiffness of the connection, and improved possibility of brittle failure of beam-to-column composite connection, and affected the damage mode to the joints with openings in the beam web. Besides, when the composite action is taken into account, the critical opening radius of the joint is larger than that not considering the composite action. At last, a reasonable opening radius is presented for the joints of steel structure of civil medium and high-rise buildings.关键词
