钢-混凝土组合梁开孔波折板连接件受剪性能试验研究
Experimental study on shear behavior of perforated corrugated plate connectors in steel and concrete composite beam
摘要
Abstract
Based on the test results of 12 groups of perforated corrugated plate connectors with different parameters, the failure modes, characteristics of load-slip behavior, impact of constructional parameters on the bearing capacity, variation rule of transverse rebar strain, and the von Mises stress curve of the shear connectors were studied by monotonic shear loading test. It can be concluded that the load-slip curve of the corrugated perforated shear connectors can be approximately divided into no slip stage, the elastic stage, the plastic stage and the the failure stage. The height of wave and the strength of concrete have great influence on the bearing capacity, shearing stiffness and the characteristics of load-slip. The von Mises stress of the welding side is greater than that of free side. The von Mises stress of the flap segment is greater than that of flat segment. The von Mises stress of the side with holes presents linearly increasing trend with the increasing load. For the specimens with the same parameters, the smaller the diameter of transverse rebars is, the larger the stress of the rebars is. The larger the height of wave is, the smaller the shear force of the transverse rebars is. Compared with perforated plate connectors, the shear capacity of perforated corrugated plate connectors without transverse rebars increases by 300% , and the shear capacity of perforated corrugated plate connectors of contain transverse rebars increases by 200%.关键词
