摘　　要：为提高装配式钢筋混凝土(RC)框架结构的抗震性能,并针对震后梁、柱构件损伤严重等问题,提出一种基于人工塑性消能铰的装配式混凝土框架-摇摆墙结构。人工消能塑性铰即梁、柱构件在梁端采用机械铰及附加耗能钢板连接的构造,基于该构造的框架结合底部铰接的剪力墙,形成人工消能塑性铰框架-摇摆墙结构。使用OpenSEES软件建立了人工消能塑性铰框架-摇摆墙模型及2组对比模型,选用24条天然地震波对3组结构模型进行双向地震响应分析,结果表明:人工消能塑性铰框架-摇摆墙结构可通过摇摆墙的构造,提升结构竖向连续刚度,使结构层间变形均匀,实现完全梁铰的理想屈服机制;在整体可控的变形模式下充分利用人工消能塑性铰滞回耗能,有效减小结构地震响应。To enhance the seismic performance of precast-reinforced concrete frame structure,and aim at the severe damage of beam and column members after earthquake.an innovative precast frame-rocking wall structure based on artificial dissipative plastic hinge construction is proposed,ADPHs are construction that connect precast beam and column though an embedded mechanical hinge,and additional steel plates are installed to carry the load and dissipate energy,combined with pin-support wall,forming the ADPH rocking wall-frame structure(ADPH-RW).In this paper,two representing 6-story ADPH-RW and ADPH models were established using OpenSEES,and one RC frame model as contrasted.The non-linear time history analyses of three models under 24 earthquake excitations are conducted.The results show that,since the promotion of vertical continuous stiffness through the rocking wall,the ADPH-RW frame are able to mean the inner-storey drift and ensure the preferable damage mode is fully beam-hinge mechanism;Under the controllable deformation mode,ADPH-RW frame could dissipate energy effectively,reduce the seismic response.
