摘要
采用有限元软件模拟单双向地震作用下框架-核心筒结构内力的受力性能,将单双向地震作用下构件内力进行对比,分析了双向地震作用对框架柱、框架梁、剪力墙、连梁内力的影响,得出了一些双向地震作用下框架-核心筒结构的内力分布规律。
Based on the finite element software,mechanical behavior of reinforced concrete frame-core tube structure under axial or bidirectional earthquake actions was studied. By contrasting mechanical performance of structures under axial earthquake action or under biaxial earthquake actions,the influence on columns,beams,shear walls and coupling beams was analyzed,and some internal force distribution rules of concrete frame-core tube structure were obtained.
