| 摘 要： | 对一榀单跨两层半刚接框架-十字加劲钢板剪力墙结构进行水平反复荷载作用下的抗震试验研究,系统分析结构破坏模式和耗能机理,研究节点刚度与加劲墙体的相互影响效果,得到了承载力,延性,刚度和耗能能力等指标。试验结果表明:该种结构具有良好的延性和耗能性能,安全储备高;节点刚度退化小,内填钢板的设置缓解了节点区自身的延性要求,半钢框架和墙板协同工作良好;加劲肋的设置改善了钢板的实际受力,提高墙体的承载力及刚度,减轻了滞回曲线的捏缩现象,减小钢板噪音及震颤。结构破坏模式为加劲肋屈曲,内填钢板以小区格局部屈曲为主,伴随相关屈曲;框架柱脚及梁柱半刚性连接部位形成塑性铰;试件面内呈弯曲破坏模式,研究为该种结构体系的工程应用和理论分析提供依据。
