摘要
在国内外复合墙研究的基础上,提出一种保温层贯通型复合剪力墙结构,为研究竖向偏心荷载对复合剪力墙受力性能的影响,对3个1/2比例缩尺复合剪力墙试件进行偏心受压试验,包括2个在偏心受压作用下的试件和1个在轴心受压作用下的试件,对比分析其破坏形态、受力性能、边缘纵筋、网架筋以及协同工作性能.试验结果表明:偏心距是影响复合墙承载力的重要因素,偏心距越大,复合墙的承载力越大;无论是偏心还是轴心受压试件,试件两侧结构层在斜插筋的连接下协同工作性能较好,设置保温层使墙体厚度增大,提高了复合墙的稳定性.
Abstract
Based on the study of the composite wall at home and abroad,this paper puts forward a kind of composite shear wall structure at through the thermal insulation layer.To study the vertical eccentric loading effect on the properties of the composite shear wall stress,the proportion of 3 1/2 scale composite shear wall specimen eccentric compression experiment was carried out,including two specimens under the action of eccentric compression and 1 under axial compression specimens,the failure modes,mechanical properties,edge longitudinal bars,grid bars and cooperative performance were compared and analyzed.The experimental results show that,whether eccentric or axial compression specimen,the structure layers on both sides of the specimen work well together under the connection of oblique reinforcement,and the insulation layer increases the wall thickness and improves the stability of the composite wall.
