高层建筑结构在竖向地震作用下的时程分析

Direct Dynamic Analysis of Tall Building Structures Subjected to Vertical Earthquake Action

本文采用了分层模型和并联多列质点振动模型两种形式，分别提出了其竖向地震作用下的直接动力分析方法，编制了面向微机的程序ＤＹＮＡ４、ＤＹＮＡ５。文中对分层模型的适用条件进行了讨论。

In this paper, the direct dynamic analysis methods using singlecolumn and multi-mass vibration model as well as using multicolumn and multi-mass vibration model have been proposed. By which the computer programs DYNA4 and DYNA5 have been compiled.Finally, the application conditions of using single-column and multi-mass vibration model have been discussed.
