（上海艾能電力工程有限公司,上海200023）[摘要] 鋼筋混凝土框架結(jié)構(gòu)是由梁板柱結(jié)構(gòu)共同組成、協(xié)調(diào)受力的結(jié)構(gòu)，通過一個(gè)典型火電廠主廠房結(jié)構(gòu)設(shè)計(jì)實(shí)例為工程背景來深入研究火力發(fā)電廠主廠房中梁剛度放大系數(shù)的應(yīng)用范圍及合理取值。最終通過對該結(jié)構(gòu)體系中梁剛度放大系數(shù)的理論分析和計(jì)算推導(dǎo)，得出其合理取值應(yīng)在1.3～1.7之間，這樣才能保證結(jié)構(gòu)達(dá)到經(jīng)濟(jì)配筋率。[關(guān)鍵詞] 中梁剛度放大系數(shù); 火電廠主廠房; 經(jīng)濟(jì)配筋率; 結(jié)構(gòu)計(jì)算中圖分類號：TU375.4 文章標(biāo)識碼：A 文章編號：1002-848X(2013)S2-0589-03作者簡介：馬波（1979- ），女，工程師，工學(xué)碩士，一級注冊結(jié)構(gòu)工程師，主要從事火電廠土建結(jié)構(gòu)設(shè)計(jì)及相關(guān)研究。Email:woshimabo@126.comApplication discussion of The middle beam rigidity amplification coefficient in the fossil fuel power plant main buildingMa bo（Shanghai Intelligence Power Company,Shanghai 200023,China）Abstract: The RC frame structure comprises beam slab and column, which work in harmony. This paper study the application range and reasonable value of the middle beam rigidity amplification coefficient in the fossil fuel power plant main building through a typical fossil fuel power plant main building structure design. Finally we draw a conclusion that the reasonable value should be between 1.3 and 1.7 through theory analysis and calculation deduction, which can ensure the structure to achieve economical ratio of reinforcing bars.Keywords: the middle beam rigidity amplification coefficient; fossil fuel power plant main building; economical ratio of reinforcing bars; structure calculation
