ANALYSIS OF SEISMIC PROPERTIES OF AN ANCIENT TOWER BEFORE AND AFTER STRENGTHENING WITH CFRP

Protection of cultural heritage structures such as the ancient pagoda from severe earthquake by conventional strengthening methods is not always reliable. In recent years carbon fiber reinforced polymer( CFRP) has been widely applied to the field of rehabilitation and retrofit of existing structures, so earthquake protection of cultural heritage structures through FRP is practicable and feasible. The seismic properties of the old tower and that with FRP are analyzed. The calculated results illustrate that the strengthening method with FRP is very effective to improve the structurecs earthquake resistance and has great potential specifically for use in ancient masonry structures.
