Experimental study on seismic behavior of shale ceramsite concrete shear walls
摘要
Abstract
With quasi-static tests, the seismic performance of five kinds of shale ceramsite concrete shear walls were studied. The effects of height-width ratios and reinforcement ratios of shear walls were considered. The failure pattern, hysteretic loops, bearing capacities, ductility, energy dissipation, stiffness of shale ceramsite concrete shear walls were analyzed. Analytical result indicates that the shale ceramsite concrete shear walls have good ductility and mechanical properties. The height-width ratio is the major factor affecting the failure mode of shale ceramsite concrete shear walls. The failure mode of shale ceramsite concrete shear wails is similar to common concrete shear wall and other light weight aggregate concrete shear wall. The failed regions of shale ceramsite concrete shear walls mainly concentrate within the width of the shear walls on the bottom above. To increase the vertical reinforcement ratio will help improving the deformation properties and the bearing capacity of shale ceramsite concrete shear walls. To increase the transverse reinforcement ratio can not proportionally improve the bearing capacity of shear walls. Based on the analogous truss model calculation theory and the dowel actions of vertical reinforcement for shear wall, the calculation formula of the bearing capacity for shale ceramsite concrete shear walls was established and the calculate results were compared with test results.关键词
