PERFORMANCE CONFORMATION TEST OF POST-INSTALLED REINFORCING BAR OF STRENGTHENED BEAM BY INCREASED SECTION

– For reuse of existing underground structure –

Abstract

For reuse of existing underground structure, we have so far carried out experimental research on reinforcement of existing RC beam by increasing section. As a part of this research, anchorage performance of reinforcing bar, anchored horizontally into existing structure by the same way as post install anchor, needs to be confirmed. This report illustrates the pull out test on post installed reinforcing bar anchored to drilled concrete hole with shear keys, with non-shrinkage cement as filler. Test results show the effects of diameter of reinforcing bar, place and number of shear key and anchor plate.
