【摘要】 为了进一步完善钢-混凝土混合结构体系的分析手段,参照框架-剪力墙协同工作模型的基本思路,在此平面二维分析模型和计算方法的基础上,考虑钢框架和混凝土核心筒之间的横向钢梁的竖向空间约束作用,建立了该混合结构的拟三维弹塑性地震反应分析方法,其主要优点在于能以简单、可行的方式处理钢框架-混凝土核心筒间的地震空间相互约束作用这一复杂问题。最后,采用此方法对算例进行了分析。更多还原

【Abstract】 In order to perfect the method to analyze the steel-concrete hybrid structures system,according to the cooperating model of the frame-shear wall structures,and based on two-dimensional elastic-plastic analysis model and the corresponding calculation method to analyze the seismic response of the steel frame-concrete tube hybrid structures,a pseudo-three-dimension elastic-plastic seismic response analysis method is estab- lished,considering the vertical spatial restrain effects of the transverse beam between steel frame and concrete tube.It can simulate the spatial restrain effects between steel frame and concrete tube simply.Then,a case is analyzed by using the pseudo-three-dimension analysis method which considered the vertical spatial restrain.更多还原
