将高层建筑结构近似地等效成非线性弹性支承梁，以悬臂梁、柱之本征函数作为Ｒｉｔｚ矢量，用能量法推导出结构的运动方程，其自由度数及计算量均比用有限元法时大为减小。用本文的方法可以计算具弹塑性铰或弹塑性耗能器之剪切墙及框架式高层建筑结构。计算结果表明，采用非线性耗能器并引进高阻尼，可以显著地降低结构之地震响应。 The high-rise building structure is approximately equivalent to a nonlinear elastic support beam, and the eigenfunctions of the cantilever beam and the column are used as Ritz vectors. The motion equation of the structure is deduced by the energy method. The degree of freedom and the calculation amount are all compared by the finite element method. When greatly reduced. The shear wall and framed high-rise building structure with elastoplastic hinges or elasto-plastic energy absorbers can be calculated by the method of this paper. The calculation results show that using a nonlinear energy absorber and introducing high damping can significantly reduce the seismic response of the structure.
