Deformation prvpagation method is used in this calculation. According to the beam end conditions, two initial variables are adapted to berived the propagated formulas by conjugate beam method, These formulas are used to calonlate internal forces and deformations at each support step by step. The initial variables are determined by end conditions at the last support. For dynamic analysis, each spar of continuous beam may be seperated in ten parts which are assumed to be supported by virtual elastic springs whose elastic constants are zero. The internal forces due to vertical deformations of beam are assumed to act on actual and virtual supports. This method may also be extended to analysic beams on elastic foundation. These computations maybe completed using PC. 1500 computer.

The high storey building structure is modeled as an equivalent cantilever beam on nonlinear supports.Its governing equations are derived by using the Ritz method, eigenfunctions of cantilever Euler-Bernouli beam being used as the Ritz vectors.Since the number of degrees of freedom in the Ritz space is much fewer than that in a finite element method, the computational work can be reduced considerably. This method can be used to analyze shear wall structures with elasto-plastic hinges or dampers as well as tall frame-type structures. Numerical results show that the seismic response of a building structure can be reduced significantly by using to nonlinear and strong dampers.

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。
