Abstract: Systems and methods are provided to detect and determine the location and relative significance of joint damage in structures including bridges, and particularly including accelerated bridge construction (ABC) bridges, based on measured changes in bridge dynamic or static response parameters and model updating methods. These systems and methods may use a detailed finite element model to calculate the sensitivity of joint damages in the structure response parameters for a particular loading configuration and the change of state in the structure obtained through instrumentation and response monitoring of the structure compared to a prior condition of the structure in order to identify potential damages.
