[提要]  對高層混凝土房屋結(jié)構(gòu)的施工過程進(jìn)行了模型化處理，建立了能反映施工過程各階段結(jié)構(gòu)受力性能的三維有限元模型和計(jì)算分析方法。工程實(shí)例的驗(yàn)證表明，計(jì)算結(jié)果和實(shí)際情況基本一致。
[關(guān)鍵詞]  高層建筑  混凝土結(jié)構(gòu)  施工階段  安全性  三維有限元模型

A model for the construction process of high-rise reinforced concrete structures was proposed. Based on the model, the safety of high-rise reinforced concrete structures in construction was analysed by using the 3-D finite element method. The theoretic results for a high-rise building which was constructed in downtown of Shanghai have good match with that observed in the construction site.
Keywords: high-rise reinforced concrete structure;  construction process;  safety;  finite element model
