无加劲冷成型方钢管-H形钢梁翼缘板焊接节点管壁变形初始刚度分析
Analysis on initial stiffness of weld-up assemblage composed of no-diaghragm cold-formed tube and flange plate of H-shaped beam
摘要
Abstract
The deformation of tube wall under the moment at the H-shaped beam end is the main component of the total joint deformation.In order to establish a mathematical answer of prediction formula for the initial stiffness of the joint, the test data of 11 weld-up assemblages composed of cold-formed tube and flange plate of H-shaped beam were used.After compared with the result of tests and fitting formula, it is reasonable to deduce the resolution of tube wall stiffness based on the elastic theory.The main parameter affecting the tube wall stiffness is the ratio of width to thickness of tube.Because of the existence of round corner of cold-formed tube, the true ratio of width to thickness of tube flange will be smaller, so the tube wall stiffness of specimens composed of cold-formed tube will be quite larger than that composed of weld-up box section.关键词
