目前各类建筑物动力特性的测试方法颇多,本文基于选频测振方法,对框架和框架剪力墙结构的两幢多层建筑物进行了脉动测试与分析,并得出如下一些结果: 1.脉动测试中采用选频方法可较为方便地取得建筑物的前几阶频率和振型。 2.利用选频方法可以对建筑物的扭转振动现象予以估计。
At present, there are many test methods for the dynamic characteristics of all kinds of buildings. Based on the method of frequency-selective vibration measurement, this paper tests and analyzes the pulsations of two multi-storey buildings with frame and shear wall structure. The following results are obtained: 1. Pulsation test using the frequency selection method can be more convenient to obtain the first few steps of the building frequency and vibration mode. 2. Frequency selection method can be used to estimate the torsional vibration of buildings.
