摘要
结构的动力特性试验旨在得出结构的自振频率、振型、阻尼系数等性质.对此类试验的理论基础本文给出详细阐述.结构动力特性是由结构本身的特性决定的,所以可以根据结构的动力特性来反映出结构本身的状态.近年来我国各种地质灾害屡屡见于报道,由此造成了众多建筑结构的损坏.而要对结构的损伤程度做出鉴定就可以通过结构动力特性试验来对损伤程度做出较为准确的判断.本文给出两个实例验证了该方法的有效性.
A dynamic property test is aimed to get the structure ＇s natural frequency, vibration mode, damping coefficient and so on. This paper discussed the theoretical foundation of the dynamic property test. The dynamic property was determined by the structure own characteristics, so the information of the structure was gotten through a dynamic property test. Recently, there have been many geological hazards broadcasted on the media, and lots of damage occurring in building structures. The dynamic property test can provide accurate structural damage identification. This paper provided two examples to prove it.
