摘要
高层建筑的动力特性是其自身固有的特性,一般是指其自振频率、振型及阻尼比。通过现场测试得到高层建筑的动力特性具有重要意义,既可以验证理论计算,又可以为建筑物的安全性评估及损伤识别积累基本技术资料。而在获取高层建筑动力特性过程中,现场测试方法至关重要,现场测试数据的精确程度决定了后续工作的成果。本文对高层建筑结构动力特性的现场测试方法进行了概括、比较与分析,并以两个实例加以论证。
The dynamic behaviors of high - rise buildings are commonly refered to natural frequencies, vibration modes and damping ratios. They can be investigated by means of field vibration test, and can be served as fundamental data for health estimation and damage identification, as well as the theoretical analysis. In the course of field test, the test methods are so important that the results of test data predominate the achievements of successive studies. In this paper, the methods of field vibration test for two practical projects are investigated.
