볼트조립식 CFT 내진보강공법에 관한 실험적 연구

Experimental Study on the Bolt Assembly type CFT Seismic Reinforcement Construction Method

The government of South Korea enacted Earthquake Recovery Plan Act in 2008. In order to meet the requirement of this law, the important buildings, such as schools, public offices and so on, are in the process of seismic retrofit. This paper introduces the experimental data about a non-retrofitted concrete column and retrofitted column with a bolt assembly type CFT(concrete-filled steel tube).
