| Abstract: |
The seismic performance of precast bridge piers with half grouted sleeves is studied by quasi-static test and compared with precast bridge pier with full grouted sleeves. The main failure modes of the precast bridge pier with half grouted sleeves are concrete crushing failure at the joint of column-to- footing and bond-slip failure of the longitudinal reinforcements in the half sleeves, there is no obvious crushing and spalling of the pier concrete. The ultimate horizontal strength of the precast bridge pier with half sleeves is small and shows a rapid decline trend after reaching the ultimate strength, hysteresis loops are flat and narrow while the residual displacement is small. On the whole, the seismic performance of the precast piers connected by half grouted sleeves is weak due to the bond-slip of the longitudinal bars in the half grouted sleeves. further researches are needed for precast bridge piers with half grouted sleeves without bond-slip behaviour. |
