摘要
随着建筑形式多样化的发展,出现了越来越多的超高层钢结构建筑,为了满足抗震设计要求,加强结构的稳定性,通常需要设置伸臂桁架来减小结构的侧移,桁架层一般都是由大型支撑杆件连接而成。基于美国AISC的相关技术标准,介绍一种大型钢结构带支撑节点设计的方法——均力法,详细介绍其设计原理、几何参数和力的关系,并结合科威特国民银行项目中桁架层巨型支撑节点实例进行应用研究。
Nowadays,more and more super high-rise buildings appear with the diversification of architectural forms. In order to satisfy the seismic design requirements and enhance the stability of super high-rise structures,the truss storey and trusses have been widely applied, which are generally composed of large bracing members to reduce the lateral displacement. Based on the specificatin of AISC,this paper introduced one method of large bracing members—uniform force method,including its design principle,the relationship between the geometry parameters of details and force,illustrated with the application of bracing connection of truss storey at National Bank of Kuwait project.
