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。
In order to find a reliable and accurate method for the elastoplastic analysis of the concrete-core-tube hybrid structure of steel frame accurately and conveniently, it is separated into reinforced concrete and steel structures. The constitutive relations and the hysteresis model, failure criterion, Then the elasto-plastic static-dynamic analysis of the hybrid structure is completed by solving the three-dimensional zonal coupling of beam elements, wall elements and finite strips respectively for the different regions and components with different elastic-plastic states. Analysis of the interlaminar displacement parameters under typical earthquake loads and wind loads shows that interlaminar shear deformation has greater influence on shear wall cracking than interlaminar bending deformation.
