基于锁铆连接传力可靠、强度优异的特征,提出了一种新型的内置铆接开孔冷弯薄壁型钢混凝土组合梁。以底部铆钉间距、截面宽度为变量,对内置铆接开孔冷弯薄壁型钢混凝土组合梁开展了四点弯曲试验,考察了该组合梁的破坏特征、承载性能和延性指标,试验结果表明:新型组合梁受弯时表现出良好的延性性能;底部铆钉间距小的组合梁延性较差;增大截面宽度可提高组合梁的极限承载力。采用ABAQUS有限元软件对该组合梁进行参数分析,重点探究五大关键参数对其力学性能的影响:有无混凝土包裹、混凝土强度、顶部铆钉间距、底部钢板厚度及截面高度 ...

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。
