[提要] 提出高層建筑框支剪力墻結(jié)構(gòu)簡化分析的超元法，即在通常的假定下，對上部剪力墻部分經(jīng)連續(xù)化處理以后，簡化為等效柱，底層框架部分在柱項轉(zhuǎn)角、側(cè)移相等的假定下，視為等代柱，整個結(jié)構(gòu)視為一個懸臂柱，然后按樓層劃分成超級單元，用矩陣位移法分析。該法結(jié)構(gòu)自由度很少，計算十分方便。
[關(guān)鍵詞] 高層建筑框支剪力墻 超元法The supcr clcmcnt mcthod is prcscntcd for analysis on tall building structure with shcar walls supportcd by framcs. Aftcr trcatmcnt of the uppcr shcar wall with continuous tcchniquc,it can be trcatcd as an cquivatcnt column. The bottom frame can be trcatcd as substitute column with the assumption of cqual slopcs and latcral displaccmcnts at the top joints of the bottom frame (the stiffncss of the crossbcams is infinitcly grcat). So,the whole structure can be considcrcd as a cantilcvcr column and is thcn analyzcd by matrix displaccmcnt mcthod,which is vcry simple in calculation.
Keywords: tall building; shcar wall supportcd by framc; supcr clcmcnt mcthod
