[摘要] 本文簡(jiǎn)要介紹了某12層頂部加鋼結(jié)構(gòu)的鋼筋混凝土結(jié)構(gòu)辦公樓的抗震計(jì)算分析，利用ETABS. SATWE 兩種計(jì)算軟件及三個(gè)計(jì)算模型，對(duì)鋼結(jié)構(gòu)與鋼筋混凝土結(jié)構(gòu)共同工作的建筑結(jié)構(gòu)的剛度、周期、位移、結(jié)構(gòu)內(nèi)力等進(jìn)行比較，指出此類建筑必須考慮鋼結(jié)構(gòu)和鋼筋混凝土結(jié)構(gòu)共同工作，采用總體計(jì)算、整體分析的必要性和可行性，對(duì)結(jié)構(gòu)設(shè)計(jì)具有針對(duì)性及指導(dǎo)意義。

Abstract: With software ETABS and SAT'WE, a reinforced concrete office building where one steel structure layer is added on its top is analyzed seismically using three kinds of computation modes. Compared the nigidity, period, displacement and inner force of original structure with the structure after adding one steel storey, we find it is necessary to analyze the whole structure due to the significance of the computation results. And the results show that the period increases and the total bottom shear force varies inconspicuously after adding one steel storey, which can guide the similar structural design significantly.
Keywords: steel adding storey; total stiffness; joint work
