Abstract

In this paper we present a new algorithm, named VTHH, used for bridge damage-location determination. This method bases on varied potential energy of vibrational bridge. We use a Neuro-Fuzzy inference system to establish the database of the notdamaged bridge, which is used to to find out the varied potential energy. A measurement system is built at HCM University of Technology to measure vibrational amplitudes of the bridge model in order to build experiments evaluating efficiency of the proposed algorithm, and comparing efficiency of this algorithm with efficiency of the energy method published.
