【摘要】 虽然钢管混凝土是由钢管和混凝土两种材料组成，但它们的共同工作是可靠的，所以根据统一理论，宏观上可视其为一种“组合材料”。本文采用钢管混凝土组合指标设计方法，对框架—抗震墙地震响应性能，进行了以下几方面的研究： (1)把由钢筋混凝土柱构成的框架—抗震墙结构与由钢管混凝土柱构成的框架—抗震墙结构作为两种方案，选取相应的动力学方程，来描述框架—抗震墙的非线性动力性能，并根据实际，选用适当的动力求解方法； (2)采用有限元分析软件ANSYS，分别建立了两种方案的结构模型，作为动力分析的基础，分析两者的自振特性； (3)按三种工况：一维、二维及三维地震动输入，分析钢管混凝土柱框架—抗震墙在一致激励下的几何非线性与材料非线性的动力特性； (4)通过两种结构体系动力特性、几何非线性和材料非线性地震响应性能的比较研究，综合评定了钢管混凝土结构的抗震性能，为该类结构的设计和施工提供了一定的参考依据； (5)采用有限元分析法，从结构整体工作性能的角度证明，钢管混凝土用于高层建筑在承载能力、变形能力、滞回耗能等抗震性能方面有突出的优点。更多还原

【Abstract】 The concrete filled steel tubular (CFST) is considered as a composite material and the co-work of steel and concrete is reliable. Depend on composite indexes design method, dynamic behavior for frame-shear wall structure were studied as follows:1. The reinforced concrete (RC) column and CFST column of frame-shear wall are used as two kinds of projects and Responsible formulations were used to describe the frame-shear wall structure’ nonlinear dynamic actions while appropriate method was chosen to solve these problems on the base of forgone researches.2.The finite element models of the structures were formed through reasonable simplification and modal shapes were studied by using the program ofANSYS.3. The frame-shear wall structure’ responses to uniform excitation of earthquake were discussed. The geometric and material nonlinear beings were considered in the horizontal, vertical and three dimensions situations.4. An RC corresponding to CFST column frame-shear wall were introduced whose responses to uniform excitations with dynamic actions, geometric and material nonlinear being considered. Comparing the calculation results, the earthquake resistant behavior of the CFST structure has been appraised synthetically which may be referenced for structure design.5.Though infinite element analysis structure and in a general behavior aspect, there were unique advantages in seismic behaviors such as higher load bearing, deformation behavior, dissipated hysteric energy and so on.更多还原
