Our primary research focus is on dynamics of structures and structural health monitoring. We investigate the dynamic behavior of structures in both in-situ and laboratory settings. We monitor the health of existing structures using wireless smart sensors. Furthermore, research is done in detecting and estimating damage using experimental modal data at laboratory setting using scaled down building models coupled with shake table. We also review wind maps from time to time in order to maintain the standards and ensure the relevance to Sri Lankan context. Currently our focus is on developing and establishing wireless sensor networks at large scale civil engineering structures and predicting the behavior of the structures and maintaining them as a living laboratory. Working together with an interdisciplinary team consisting of professionals form structural engineering, electronics and telecommunication engineering, integrated circuit engineering, we do cutting edge research which aims to bridge the gap between the performance of real structures and the results from laboratory tests done on scale models.
