Compared with the traditional construction method of overall cast-in-place bridge piers,precast bridge piers technology is conducive to shortening the construction period,lessening the damage on the environment and guaranteeing the construction quality.The seismic performance of precast reinforced concrete bridge piers is one of the key points to the design of precast bridge piers.One set of specimens with cast-in-place type and two sets of specimens with precast type are designed and studied on destruction...
