Realization of monitoring and diagnosis of structural health need advanced technologies, such as information technology, system identification, sensor technologies, model updating, and damage detection algorithms, in order to prevent catastropic collapse of built civil infrastructure under ordinary conditions and extreme natural disasters.  Our group has been conducting research on vibration based algorithms for structural damage detections, system identification, real-time reference-free monitoring techniques, model updating and development of a collaboratory system for remote experiments. Particularly, a 3D recongifurable truss structure is available for advanced research in the field of structural health monitoring.
