| Abstract: | 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. |
