[摘要] 確定地下室頂板能否作為上部結(jié)構(gòu)的嵌固端時(shí)，必須要考慮地下室與上部結(jié)構(gòu)的側(cè)向剛度比不小于2的要求；但是現(xiàn)行規(guī)范中沒(méi)有規(guī)定計(jì)算地下室側(cè)向剛度的有效范圍。本文通過(guò)建立高層框架結(jié)構(gòu)的簡(jiǎn)化模型，用SATWE分析高層建筑結(jié)構(gòu)的動(dòng)力、內(nèi)力與變形特性，證實(shí)并探討影響結(jié)構(gòu)特性的地下室有效范圍。

Abstract: To ensure whether the superstructure can be fixed on the top slab of the basement, the ratio between the lateral rigidity of the basement and that of the upside adjacent floor structure is required to be no less than 2. However, the effective scope of the base to calculate lateral rigidity hasn't been confined in the current norm yet. Since then, according to the study of dynamic characters, inner force and deformation of a simplified high-rise frame structure model with the help of the software SATWE, the effective scope of the base that can influence the global structural properties is verified and analyzed in this paper.
Keywords: high-rise building;  build-in;  lateral rigidity;  ratio of rigidity
