摘要
本文介绍了高层建筑模型的随机激振实验和模态参数识别方法,给出了前8阶模态参数。在7T17S 信号处理器荧光屏上显示出三维主振型的动画图象,并一一拷贝印出。本文还对如何确保模态参数识别精度进行了分析讨论。实验所得模态参数可用于动态计算方法的验证以及用于楼房原型动响应计算和设计。
Random excitent testing and method of identifying modal paramenters for the model of a tall building are presented in this paper.First eight modal paramenters are gave and every three-dimensional mode shape is displied movingly on screen of Signal Processor 7 T 17 S and is copied.In addition we discussed how to ensure identifying precision of modal paramenters in the paper.The modal paramenters of the model obtaining from the tensting are able to use to verify dynamic calcunation method and to design the hight building.
