A system and method for measuring dynamic properties of a structure and for assessing dynamic performance of a structure using the measured dynamic properties. The system and method may separate the measurement response into low amplitude data and high amplitude data to reduce the effects of mass and external forces. The system and method measures dynamic properties of the structure, such as resonant frequency, mode vibration mode, and non-linear damping, and uses them for structural analysis to compare the dynamic response of the structure to expected properties of the structure built according to applicable building specification requirements. Thus, the system and method quantify the risk of failure of the structure by determining a risk ratio that compares the original condition of the structure to the design condition of the structure. 一种用于测量结构的动态性质并且用于使用测量的动态性质来评估结构的动态性能的系统和方法。该系统和方法可以将测量响应分离成低振幅数据和高振幅数据，以减少质量和外力的影响。该系统和方法测量结构的动态性质，诸如共振频率、模式振型和非线性阻尼，并将它们用于结构分析以将结构的动态响应与根据适用的建筑物规范要求建造的结构的预期性质进行比较。因此，该系统和方
