（上海艾能电力工程有限公司,上海200023）[摘要] 钢筋混凝土框架结构是由梁板柱结构共同组成、协调受力的结构，通过一个典型火电厂主厂房结构设计实例为工程背景来深入研究火力发电厂主厂房中梁刚度放大系数的应用范围及合理取值。最终通过对该结构体系中梁刚度放大系数的理论分析和计算推导，得出其合理取值应在1.3～1.7之间，这样才能保证结构达到经济配筋率。[关键词] 中梁刚度放大系数; 火电厂主厂房; 经济配筋率; 结构计算中图分类号：TU375.4 文章标识码：A 文章编号：1002-848X(2013)S2-0589-03作者简介：马波（1979- ），女，工程师，工学硕士，一级注册结构工程师，主要从事火电厂土建结构设计及相关研究。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
