摘　　要：将超高层连体结构等效连续化为连体T imoshenko梁,用哈密顿原理推导控制方程和边界条件,以常微分方程求解器(ODE)为工具,在弹性范围内对超高层连体结构进行了自由振动分析计算。通过算例结果与通用有限元软件s ap2000分析结果对比表明,此简化分析方法是合理的,结果满足工程精度要求。When super-tall connected building structure is realized by the equivalent continuum Timoshenko beam,the control equation and the boundary conditions could be deducted with Hamiltonian principle and the free vibration analysis of the super-tall connected building structure could be worked out in elastic extent by means of ODE.Contrast of example results with analysis results from finite element software sap2000 proves this simplified method rational and the result will meet the engineering precision requirements.
