| Research Abstract |
Real-scaled RC columns exposed at coastal area in Okinawa, since 2004 to 2010 to find out the durability and seismic performance of RC columns damaged by chloride attack. The RC columns were tested under reversed cyclic loading and constant axial force. As a result, the durability and seismic performance of RC columns exposed for six years decreased in comparison with the benchmark specimens kept in out-of coastal area conditions. In flexure and shear strength calculations of chloride-attacked RC columns, the weight reduction ratio method is used for the reinforcements, and the estimated calculations agree with the experimental results.
