单节段装配式桥墩抗震性能试验研究
Experimental study of seismic performance of single segmental precast bridge piers
摘要
Abstract
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 forms, horizontal bearing capacity, ductility and accumulated energy dissipation,etc..by using quasi-static tests.The experimental results show that compared with overall cast-in-place piers,precast bridge piers have a similar horizontal bearing capacity,a little poor performance on displacement ductility and accumulated energy dissipation and a bigger residual displacement;the displacement ductility and accumulated energy dissipation of precast bridge piers using steel sleeve connection are better than precast bridge piers using metal bellow connection.关键词
