[提要] 對考慮樓板變形的變截面框-剪結(jié)構(gòu)的二階分析問題建立了一個分段連續(xù)化的串并聯(lián)模型,導出其二階分析的微分方程組,用常微分方程求解器求解。討論了影響二階效應的一些因素。

The second-order analysis differential equations for the model are then derived. Morever, the second-order displacements and internal forces are determined numerically by means of the ODE (Ordinary Differential Equation) solver, which is a program developed for solving various ODEs. Lastly, the factors that influence the second-order effects are discussed.
Keywords: tall building structure; second-order analysis; floor slab deformation
