摘要

本文进行某多层砌体结构教学楼环境振动试验,利用基于传递率参数识别方法进行教学楼动力参数识别,并与该楼MI-DAS三维有限元模型理论计算结果进行比较,得出一些有价值的结论。
In this paper,the ambient vibration field-testing of a multi-story masonry structure teaching building was conducted firstly and the dynamic system parameters was identified in the frequency domain by transferring rate method.The 3-D finite element model of MIDAS was constructed and the theoretic modal analysis was performed to generate natural frequencies and mode shapes.Some important results were obtained by comparing the testing modal with the theoretic modal of the teaching building.
