翼缘双摩擦面Z形悬臂梁式全螺栓连接梁柱节点抗震性能研究

open access: yesJianzhu Gangjiegou Jinzhan
为研究所提出的新型翼缘双摩擦面Z形悬臂梁式全螺栓连接梁柱节点的抗震性能,设计相关试件进行拟静力试验和有限元分析。同时利用有限元模拟对新型梁柱节点进行参数化分析,以验证节点的适用性及设计方法的合理性。研究结果表明:新型节点发生梁端受弯破坏,最终在悬臂梁翼缘与钢柱焊接处开裂;翼缘螺栓连接段内无滑动现象,滞回曲线饱满无捏缩;连接节点的承载能力强,变形能力良好;有限元分析结果与试验结果吻合良好;当按等强连接配置螺栓时,不同截面尺寸节点模型的滞回性能相近,破坏模式相同,可按规范规定的刚接节点设计方法进行设计。
