RETROFITTING OF STRUCTURES

The research team on Retrofitting of Structures is mainly focused on the behaviour of structural ele-ments retrofitted using fibre reinforced polymer (FRP) materials. Current research work is on evaluating the structural and thermal performance of FRP retrofitted structures. We are focusing on enhancing the performance of both new and deteriorated structures by FRP strengthening. Studies are based on both laboratory experiments and numerical modelling using FE packages. During the past decade our team has produced over 70 publications in refereed journals and conferences, a selected list of which appears below.
