Simulation Analysis on Bending Performance of Bundled Lipped Channel-concrete Composite Shear Wall Considering Bottom Reinforcement
摘要
Abstract
Bundled lipped channel-concrete composite shear wall is a new type of shear wall structure with strong bearing capacity,excellent lateral stiffness and ductility. According to the failure mode of bottom local buckling,an improved method of bottom reinforced bundled lipped channel-concrete composite shear wall is presented in this pa-per. Abaqus finite element software is used to simulate and analyze the effects of the height and thickness at bottom reinforcement area on the bearing capacity and deformation capacity of the shear wall,and the effect of axial com-pression ratio on the bottom buckling of bundled lipped channel-concrete composite shear wall is discussed. From this research,it can be concluded that the bottom reinforcement method can move the bottom buckling position of bundled lipped channel upward, and the performance of concrete and bundled lipped channel can be efficiently used,thus the bearing capacity and deformation capacity of shear wall are improved significantly. The improvement of bundled lipped channel-concrete composite shear wall is optimum when the height of bottom reinforcement area is about 0.5 times the height of the wall. With the increase of the axial compression ratio,the buckling of steel tube at the bottom is aggravated,and the bearing capacity and deformation capacity decline.关键词
