摘要
简单介绍了某广场钢结构裙房大尺寸KT型相贯方钢管节点的基本特征,使用有限元软件Ansys对这种节点进行非线性静力分析.采用实体单元建模,研究多杆件同时加载条件下,该节点受力性能的变化,并分别跟踪绘出节点在不设内部加劲肋、设两个内部加劲肋、设四个内部加劲肋情况下的极限承载力曲线.通过比较各曲线异同,得出最合适的加劲方法.
This paper briefly introduced the chief distinguishing features of the large size KT square tubular joints of a steel podium. Finite software Ansys was adopted in carrying out the nonlinear analysis of this kind of joint, in the process of which, a number of structural bars were loaded simultaneously. After modeling those joints by solid element, ultimate capacities of the joints were tracked in the case of chord members with no stiff- eners, with two stiffeners and with four stiffeners respectively. The most useful stiffening method is come up by comparing the load - displacement curves extracted from analysis results.
