摘要
用Rayleigh-Ritz能量法对高层框筒结构进行整体稳定和二阶分析.首先把实际框筒结构连续化为正交异性折板结构,然后用Rayleigh-Ritz能量法建立结构的整体稳定和二阶分析的基本方程;分析了“剪力滞后”效应对框筒结构整体稳定和二阶位移的影响.
This paper deals with the overall stability and second-order analysis of framed tube structure of a tower by Rayleigh-Ritz energy method. First, the real framed tube structure is reduced to equivalent orthotropic continua. Second, the Rayleiht-Ritz energy method is used to set up the basic equation of overall stability and second-order analysis. The influence of shear-lag on overall stability and second-order displacement of framed tube structure is studied as well.
