摘要
为研究梁柱式胶合木结构体系的抗侧力性能,对10榀单层单跨梁柱式木框架足尺试件进行了水平荷载试验,其中2榀为单调加载,8榀为低周反复加载,考虑了4种抗侧加强结构体系,即交叉支撑、人字撑、隅撑以及填充轻木剪力墙.根据试验现象和由试验数据获得的滞回曲线、骨架曲线、刚度退化曲线、强度退化曲线、耗能曲线等研究了各抗侧力体系的变形能力、耗能能力、破坏模式等抗震性能,结果表明,交叉支撑、人字撑结构体系表现出良好的抗侧刚度,但二者延性较差;隅撑结构体系抗侧刚度较纯框架结构体系有了一定的提高,延性好于交叉支撑、人字撑结构体系;填充轻木剪力墙结构体系表现出良好的抗侧刚度和延性.最后,分析了各抗侧力结构体系的薄弱部位,并提出了改善加强措施.
