摘要
本文从一般高层建筑框架体系构造上多层重复特点出发,采用变分方法推导了平面框架近似动力微分方程,从而为从整体上分析框架结构的性态提供了理论工具,还给出了静力解析解,算例表明效果良好。
In this paper, according to the repeated characteristics of tall many-stories building for frame structures, we use variational principle to derive the approximate dynamical differential equations for them Thereby. it makes an offer of the theoretical tool for global analysis on those structures. The statical analytic solutions are also given. The results of solving the examples satisfied us. it demonstrated that those analytic methods took in excellent effect.
