[摘要]采用有限元軟件模擬單雙向地震作用下框架-核心筒結(jié)構(gòu)內(nèi)力的受力性能,將單雙向地震作用下構(gòu)件內(nèi)力進(jìn)行對比,分析了雙向地震作用對框架柱、框架梁、剪力墻、連梁內(nèi)力的影響,得出了一些雙向地震作用下框架核心筒結(jié)構(gòu)的內(nèi)力分布規(guī)律。

Abstract: 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.
Keywords: steel reinforced concrete frame-core tube structure; mechanical behavior; bidirectional earthquake actions; numerical simulation
