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。The RC frame structure comprises beam slab and column,which work in harmony.Study the application range and reasonable value of the middle beam rigidity amplification coefficient in the fossil fuel power plant main building was studied 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.
