摘要
根据钢框架强柱弱梁的抗震设计原则,按照使梁上塑性铰位置远离节点区的设计思路,对梁端翼缘扩大型钢框架梁柱节点进行了非线性有限元分析,并对该节点的基本受力性能和塑性区分布做了详细探讨,给出了侧板长度及宽度等尺寸参数的影响规律和有效取值范围。结果表明梁端翼缘扩大型钢框架节点具有理论上的合理性和实用上的可行性,可达到塑性铰外移和增加使用功能的目的。
According to the strong column weak beam principles of anti-seismic design of steel frames, and based on the idea of making plastic hinges of beams away from connection area, the nonlinear finite element analysis of beam to-column connections with flange haunch of beams is conducted. The elasticplastic behaviors and the distributions of plastic area are analyzed detailedly with different haunches＇ length and width. The reasonable design methods and scope of these parameters are obtained. It is shown that the design concept of the connection is theoretically feasible and practical in application to make the plastic hinge away from the connection.
