摘要
对分层法计算多层三跨以上框架竖向荷载计算中跨梁的线刚度修正系数的取用问题进行了分析,通过采用不同方法进行计算对比,提出了跨梁的线刚度修正系数取1/2比取2更接近实际情况的观点。
This paper analyzes the value of linear stiffness correction coefficient of middle-span beam with theory of hierarchies to calculate the vertical load of multi-layer frame structure,calculates and compares them by using different methods,and finally puts forward that the value of linear stiffness correction coefficient of middle-span taking 1/2 is rather closer to the actual situation than taking 2.
