TECHNOLOGY TO RESTORE THE INCLINED RC T TYPE PIER WITH THE PLASTIC HINGE

Abstract

The RC T type pier discussed in this paper was severely damaged by the Great Hanshin Earthquake. And the jack-up method was employed to correct this RC pier which had inclined approximately 2.2 degrees in the transverse direction by rotating around the plastic hinge near the lower end of the pier.
Before the restoration work, we carried out the experimental studies and the numerical studies by non-linear analysis in order to make the restoration work effective. And the inclination was corrected successfully by the jack-up method.
