| 摘 要： | 为了分析TX型方钢管相贯节点在复杂边界条件下X支管平面内抗弯刚度的影响,以相贯节点足尺试验为基础,采用量纲分析得到影响相贯节点抗弯刚度的主要无量纲参数,利用有限元软件分析X支管平面内抗弯刚度受主要无量纲参数的影响,并展开研究.试验表明：主管的轴向拉力可以略微提高X支管平面内抗弯刚度.通过分析几何因素对抗弯刚度的影响,结果表明：X支管平面内抗弯刚度主要取决于X支管与主管的宽度比和宽厚比.

| Abstract: | In order to analyze the influence of in-plane bending stiffness of X branch pipe under complex boundary of spatial TX-type square steel tubular joint,we got dimensionless parameters which influence bending stiffness of tubular joint through dimensional analysis based on full-scale test of tubular joint.Meanwhile,we analyzed and studied main dimensionless parameters＇ influence on in-plane bending stiffness of X branch pipe using finite element software.The test shows that axial tension of the main tubular can slightly improve in-plane bending stiffness of X branch pipe.Through the analysis of geometrical factors＇ influence on bending stiffness,the result shows that in-plane bending stiffness of X branch pipe mainly depends on the width ratio of X branch to main tubular and width-thickness ratio of the main tubular. |
