无加劲冷成型方钢管-H形钢梁翼缘板焊接节点受拉性能试验研究
Experimental study on load carrying capacity of welded joint assemblage between no-diaphragm cold-formed rectangular tube column and flange plate of H-shaped beam under statically tensile load
摘要
Abstract
In order to study the characteristics of the no-diaphragm joint connecting the cold-formed tube column and the H-shaped beam, 11 specimens consisting of flange plate of H-shaped beams that were welded to rectangular columns at flange plates were tested under statically tensile load considering the effect of molding types, location of seams of tube column, the restriction of flange plates in the orthogonal direction and the dimension parameters of tubes and flange plates.After the test some conclusions can be drawn that the load carrying capacity and stiffness of cold formed section specimens are higher than the welded section one.The location of tube seams has almost no effect on the capacity and initial stiffness of the connection.The restraints in the orthogonal direction makes the initial stiffness of specimens a little higher.When the end of flange plate is hunched, the average stress of the flange plate will be higher.The most important parameters which affect the capacity of joints are the ratio of width to thickness of tube section, the ratio of width of flange plate to that of tube and the ratio of flange plate thickness to the tube thickness.关键词
