建筑物结构动态参数测试研究
The Test of building structure Dynamical Parameters
【摘要】 用现代测试手段分析并验证平安大酒店建筑设计的抗震可靠性,同时提供结构动态参数、固有频率、振型及阻尼比,根据其动态参数变化,识别该结构的内部损伤,从而决定是否需要采取加固措施
【Abstract】 The purpose of this experiment is to test and verity the antiseismic reliability of the original design, andprovides the structure druamical paramters, the vibration frequency model shape and damping ratio for long termsafety measurement of the structure. After the structure is damaged by seismic, we can identify the damage of thestructure with variation of dynamic paramters.
