摘    要:为寻求一个准确、便捷地对钢框架 混凝土核心筒混合结构弹塑性分析的可靠方法 ,将其分离为钢筋混凝土和钢结构 ,分别研究其材料或构件的本构关系及滞回模型、破坏准则 ,然后针对混合结构弹塑性状态不同的区域和构件分别应用梁元、墙元、有限条三维分区耦合进行求解 ,来完成整个混合结构的弹塑性静动力分析。对混合结构在典型地震荷载和风荷载作用下的层间位移参数分析结果表明 ,层间剪切变形比层间弯曲变形对剪力墙开裂影响要大。

关 键 词:混合结构  分区耦合法  层间位移  参数分析  滞回模型  弹塑性分析

Abstract:An efficient and accurate approach for analyzing the elasto plastic seismic response of steel frames and concrete core tube hybrid structure(SFCTHS)is explored through experimental study and theoretical analysis.Elasto plastic finite wall elements with smeared cracks and elasto plastic finite strips are employed for the analysis of the different zones of the shear walls according to the stress distribution.Elasto plastic hinge model is used to solve elasto plastic behavior of steel beam.Through calculating structure examples,the cracking characteristics of shear walls and the weak aspects of the hybrid structure under earthquakes and winds are revealed.Furthermore,the parameter study on storey drifts of SFCTHS shows that it is not appropriate that the storey drift limits given by the code do not consider the effects of shear deformation.
Keywords:steel  concrete hybrid structure  zone  based coupling method  parameter study  storey drifts  hysteresis model  elasto  plastic analysis
