Tests of Slab-Column Connections with Partially Debonded Reinforcement under Cyclic Lateral Loading

부분적인 비 부착 철근을 갖는 슬래브-기둥 접합부의 반복 횡하중 실험

This article summarizes tests conducted on two full-scale interior slab-column connections with and without partially debonded reinforcement subjected to cyclic loading. Each test specimen consisted of a 4.2m square slab with a 355mm square column protruding 1.5m above and below the slab. The slab thickness was 152mm. The specimen with partially debonded reinforcement exhibited more lateral drift capacity than did the specimen with fully bonded reinforcement. With partial debonding of the flexural reinforcement, cyclic load appeared to produce less damage to the connection in the vicinity of the slab-column joint region.
