| 摘 要： | 为使钢框架梁柱节点满足强柱弱梁的抗震设计原则,并使梁上塑性铰远离梁柱节点区,对梁端翼缘扩大型(包括侧板加强型和翼缘端部放大型)钢框架梁柱节点进行了往复荷载下的试验研究,得到了节点类型和梁端翼缘扩大尺寸对节点滞回性能、延性和耗能能力等指标的影响规律.在使用非线性有限元程序对试验结果进行数值模拟的基础上,研究了梁端翼缘扩大段的长度及宽度等参数对节点性能的影响规律和有效取值范围,给出了实用设计方法.使用梁端翼缘扩大型钢框架节点可以有效实现梁端塑性铰外移,是一种在抗震设计中值得推广的具有良好延性和塑性转动能力的新型节点形式.

| Abstract: | To satisfy the strong column and weak beam principles in the seismic design of steel frames,and to keep the plastic hinge of beam away from the connection area,experimental investigation on the beam-to-column connections with beam-end horizontal haunches under cyclic loading was performed.The influences of connection type and haunch sizes on the hysteretic behavior,ductility and energy dissipation capability were studied.Based on the numerical simulation to test results using nonlinear finite element method... |
