摘要
为研究钢框架-预制混凝土抗侧力墙板装配式结构体系(SPW体系)的基于性能的抗震设计方法,对4榀钢框架-预制混凝土抗侧力墙板结构足尺试件进行低周反复荷载作用下的试验研究。对SPW体系的抗震性能水平及性能指标的量化进行研究,提出5个性能水平的失效判别标准,并给出不同性能水平对应的层间位移角限值建议;提出SPW结构体系直接基于位移的抗震性能设计方法和设计步骤,并通过算例给出16层SPW结构体系的基于性能的抗震设计过程。实验结果表明:该结构体系为一种典型的双重抗侧力体系,加载过程呈现出明显的2个阶段性,抗侧力墙板为结构体系的第1道防线,钢框架为结构的第2道防线。
In order to research the performance-based seismic design method of steel frame-concrete lateral force resisting wall fabricated structures, four full scale specimens were tested under the cyclic horizontal load. Seismic performance levels and quantitative index of SPW system were analyzed; failure criteria of five performance levels was put forward, and storey drift ratio limitation for the five performance levels was suggested. The performance-based seismic design method and procedure of SPW system were proposed for SPW system, and the design process was presented through the example of 16-storey SPW system. Experimental results show that the structure is a kind of typical double lateral force resisting system. The concrete lateral force resisting wall is the first line of defense for the structural system, and the steel frame is the second line of defense.
