Rectangular hollow bridge piers are commonly used for flyover and bridge infrastructure construction in countries with active seismic activity such as Taiwan, Japan and China due to its higher ductility and low contribution of mass to seismic response. Due to increasing live load with time as traffic level increases, structural strengthening work of hollow bridge piers are necessary to extend service life of bridge or flyover infrastructure. Fibre Reinforced Polymer (FRP) wrapped hollow column also has improved seismic energy and static load dispersion capacity and suitable to be used as...
