摘要:探討了帶豎縫鋼板剪力墻(SPSWS)框架體系中要素特性配置原則,建立了二重抗側結構體系的概念模型,得到了體系的力變形特征曲線,研究了構件要素特性配置的基本關系;建立了包含用桿件簡化的SPSWS構件和鋼框架的有限元模型,并對概念模型進行了檢驗。結果表明:概念模型所做的假定成立,SPSWS鋼框架體系中構件要素特性配置關系可以由體系的延性和承載力要求得出。

Configuration of Lateral Forceresistance Component Properties in

(1. School of Civil Engineering, Tongji University, Shanghai 200092, China; 2. State Key Laboratory for
Disaster Reduction in Civil Engineering, Tongji University, Shanghai 200092, China)Abstract: The principles of the configuration of component properties in steel plate shear wall with slits (SPSWS)frame structures were discussed, conceptual model of structures with two earthquakeresistance systems was established, forcedeformation characteristic curves of the system were obtained, and the basic relations of configuration of component properties were studied. The finite element models composed of wiresimplified (SPSWS) components and steel frames were designed to verify the conceptual models using nonlinear monotonic calculation. The results show that the conceptual model is reasonable, and the configuration of component properties in SPSWSsteel frame systems can be derived considering the requirement of ductility and bearing capacity.

0引言
鋼板剪力墻結構是20世紀70年代發(fā)展起來的新型抗側結構體系。現(xiàn)有的研究表明,該體系具有較大的彈性剛度、較好的變形能力和滯回性能,是一種高效的抗側結構體系。
帶豎縫鋼板剪力墻(Steel Plate Shear Wall with Slits,SPSWS)是最近幾年逐漸開始應用于結構抗震體系的鋼板剪力墻的一種,具有良好的耗能性能,且具有剛度、強度參數(shù)相對獨立,可以分別設計的優(yōu)點。各國學者已經(jīng)對SPSWS構件進行了大量的理論分析和試驗研究[116],他們集中于對SPSWS構件關鍵參數(shù)(抗側剛度和承載力等)的推導和驗證以及對其穩(wěn)定性、滯回性能和簡化模型的研究,但是對于如何合理配置結構體系中SPSWS和框架結構的抗側剛度和屈服承載力等參數(shù)還缺少深入研究和指導原則。……
