钢管腹板削弱型梁柱弱轴连接的抗震性能影响因素分析
在节点域箱形加强式工字形梁柱弱轴连接和钢管腹板削弱型(tubular web reduced beam section,TW-RBS)连接的基本形式上,提出了一种工字形柱与H形梁的钢管腹板削弱型弱轴(weak axis tubular web reduced beam section,WA-TW-RBS)连接。设计了3个系列共14个WA-TW-RBS弱轴连接节点的对比分析模型,采用有限元软件Abaqus对钢管的直径、厚度以及钢管中心距蒙皮板外边缘的距离进行了变参数分析,研究这些参数的变化对节点滞回性能、刚度退化、节点延性和塑性转动能力的影响。研究结果表明:在上述参数合理的取值范围内,WA-TW...
