榫卯式连接钢框架节点承载力性能研究
|
摘要
提出了一种新型钢结构梁柱连接节点——方钢管榫卯节点。对由该节点连接的钢框架结构进行了静力载荷试验,得到梁跨中和端部节点荷载-位移曲线,以及框架不同部位荷载和应变图,分析了试验的结果;并根据试验模型进行了计算机非线性有限元分析,分析了节点处构件不同截面尺寸对节点承载力的影响。提出了方钢管榫卯节点承载力的计算公式,并将它与试验结果进行了比较,比较接近。试验表明:这种新型榫卯节点承载力高,从设计原则看是可行的。
A new connection method used between beam and column in steel structure named square steel tube mortise and tenon joint is presented in this paper. The displacement curve of the beam span and end node load is got after the static load test of the steel frame structure connected by the nodes,as well as the load and strain diagram of the different parts of the framework,and then test results are analyzed. What's more,nonlinear finite element analysis with computer is carried out according to the test model,and the influence of different section size of the node elements on the bearing force of node is also analyzed. The calculation formulas of bearing capacity of square steel tube joints put forward are approximate to the test results. The experiments indicate this new type of mortise and tenon joints is of high bearing capacity and acceptable from the angle of design philosophy.
