摘要:
圆钢管相贯节点是钢管结构中常见和广泛应用的节点形式,也是一种典型的半刚性连接节点.首先介绍了关于圆钢管相贯节点刚度定义的两种方法:直接法与间接法.在此基础上,以最常见、形式最简单的Y型与X型圆钢管相贯节点为研究对象,详细阐述试验或者有限元分析中分别采用直接法、间接法获得节点的轴向与抗弯刚度的测点布置与方法及注意事项;利用已有试验数据并结合有限元分析对两种方法所得刚度值进行对比,结果表明两种方法所得结果非常接近,可根据获得测点数据的便利性而选用一种方法,如试验采用间接法、有限元采用直接法
Abstract:
Unstiffened CHS-joints is one of the common and widely used configurations for the connection of steel tubular structural members, and the joint also is a typical semi-rigid connection. The two different methods(namely direct method and indirect method) for the stiffness definition of unstiffened CHS-joints are introduced in this paper. Then, it takes two simple and common configuration of unstiffened CHS-joints (namely Y-joint, X-joint) as the object of study. The location of measure points(or displacement sensors),concrete step and matters need attention from the two methods with the tool of FEA(or test)in order to obtain axial stiffness and flexural rigidity of the two type CHS-joints elaborated in the paper. By means of test data and FEA, it show that there is little difference between the result from direct method and indirect method for the axial stiffness and flexural rigidity of the joints. Hence, one of the methods is selected according to the convenience of measured data obtained, for instance, indirect method and direct method are selected by experiment and FEA individually
