中文摘要：

消能连梁采用阻尼器耗能,保护混凝土主体结构,是近年来发展出来的一种有效的高层结构消能减震体系。本文针对带消能连梁的框架剪力墙结构体系进行整体有限元分析,研究了具有不同层数的框架剪力墙结构地震响应,分析消能连梁的能量耗散情况和对整体结构动力响应的控制效果,研究表明消能连梁能够分别降低首层墙肢和框架的能量耗散的65.5%和39.0%,同时可降低结构35.4%-42.0%的层间位移角和41.0%-44.4%的基底剪力。随后对某一18层高层建筑进行了子结构混合试验研究,试验体底部为6层联肢墙,采用1/3缩尺,其余结构分为上部剪力墙数值子结构和框架数值子结构,分别采用ABAQUS软件进行分析,三者协同工作,共同完成大震响应模拟。子结构混合试验结果表明,消能连梁可有效降低结构的整体响应,层间位移角降低16%、基底剪力降低21%。同时可控制连梁损伤,提高结构耗能能力。

英文摘要：

Energy-dissipative coupling beams adopt dampers to consume the seismic energy,so that the concrete part of the structure can be protected,which is an effective seismic mitigation system for high-rise buildings developed recently. Finite element models are constructed on reinforced concrete（ RC） frame-wall structures and time history analyses are conducted. The energy dissipation and the story drifts were evaluated for the structures with different height,and it is found that the energy-dissipative coupling beams can reduce energy dissipation of the firststorey wall and frame by 65. 5% and 39. 0% respectively,and storey drift by 35. 4% to 42. 0%,and basic shear force by 41. 0% to 44. 4%. Then a substructure hybrid testing was conducted to explore the seismic performance of a 18 story high,damage-controlled RC wall-frame building. The bottom six-story RC wall was taken as the tested substructure and scaled to 1 /3 of the prototype,while the rest of the wall was treated numerically by ABAQUS,and the RC frame was implemented as another numerical substructure,also analyzed by ABAQUS. The comparison be-tween the damage-controlled structure and the traditional RC structure demonstrates that,the energy-dissipative coupling beam can reduce the storey drift by 16. 0%,and the base shear force by 21. 0%. It is also able to control the damages of RC parts,so that improves the seismic performance of high-rise RC buildings.
