| 摘 要： | 针对钢框架梁端翼缘扩大型节点进行4个1∶2缩尺比例的模型试验,深入研究梁端翼缘侧板加强型节点和梁端翼缘圆弧扩翼型节点在低周往复荷载作用下节点的屈服荷载、极限荷载、滞回曲线、骨架曲线、延性和耗能能力等抗震性能。为了比较分析,还设计制作了1个普通栓焊节点试件。试验结果表明,4个梁端翼缘扩大型梁柱节点均达到了抗弯钢框架连接的抗震要求,而普通栓焊节点试件由于梁柱焊缝根部的脆性破坏制约了梁柱节点的塑性发展;梁端翼缘侧板加强型节点由于侧板与梁翼缘对接焊缝的影响使得焊接热影响区母材变脆而发生脆性撕裂,致使节点的耗能性能受到影响;梁端翼缘圆弧扩翼型节点的抗震性能优于梁端翼缘侧板加强型节点。建议在实际工程中,采用圆弧渐进式过渡的梁端翼缘扩翼型节点,可以有效保证梁柱节点连接的塑性变形和耗能能力。
