| 摘 要： | 以强震区多高层钢结构框架的梁柱边节点为研究对象，通过3个足尺T形截面钢异形柱-钢梁节点试件在低周反复荷载作用下的拟静力试验，研究了试件的变形、应变分布、破坏模态，得到了试件的滞回曲线、骨架曲线、承载能力、节点域的剪切变形、转动能力、延性性能、耗能能力等抗震性能指标，分析了节点域强弱对抗震性能指标的影响。试验结果表明，T形截面钢异形柱-钢梁节点在破坏前经历充分的塑性变形，其破坏模态为局部屈曲破坏，塑性铰出现于远离梁柱焊缝的梁截面上且发展充分，有较高且稳定的承载能力，具备较好的塑性转动能力、延性性能和耗能能力，能够在强震区使用。研究为此类节点的工程应用和钢异形柱结构技术规程的编制提供依据。图11表6参18

| Abstract: | Quasi-static tests on three full-scale specially shaped columns with T-shaped section to steel beam connections were conducted under low cycle load reversals to study the behavior of exterior beam to column connections of multi-story or high rise buildings in high seismic regions.The deformation characteristics,strain distribution and the failure mode were investigated.The hysteretic loops,skeleton curves,bearing capacity,shear deformation of panel zone,rotation,ductility and energy-dissipation were obtaine... |
