Abstract

In paper after the strong earthquake of recently the Korea neighborhood, the Korean government survey show that the 86% of school buildings in Korea are in potential damage risk and only 14% of them are designed as earthquake-resistance buildings. Earthquake Reinforcing projects of school have been a leading by the ministry of education, however their reinforcing methods done by not proved a engineering by experiment which results in uneconomical and uneffective rehabilitation for the future earthquake. An experimental and analytical study have been conducted for the shear reinforcing method of RC beam by axis and horizontal axis load using attaching composite beam. Based on the previous research, in this study, design examples are given to show the performance evaluation for the column reinforcing of old school buildings using nonlinear analysis is going to be conducted and strengthening method is going to be on the market after their performance is proved by the test.

이 논문에서는 한국인근에서 강한 지진이 발생된 후 조사한 국내의 학교건물의 경우 86%가 지진에 취약한 것으로 나타났으며 내진설계가 된 학교건축물은 14%에 불과한 것으로 파악되고 있다. 이에 국내에서는 교육부가 주도하는 학교건축물의 내진보강프로젝트가 수행되고 있으나, 일본 등의 다양한 시스템내진보강에 대해서는 기술과 공법 등이 도입되어 국내의 실정에 맞는지 검토 및 검증 절차 없이 적용되고 있으나 부재내진보강에 대해서는 시스템내진보강에 밀려 실무적용 및 연구가 미비한 실정이다. 그러므로 최근에 부착 및 래핑형 복합재료를 이용한 기둥전단보강방법에 관한 실험 및 이론적인 연구를 진행하였다. 이 연구에서는 기존의 연구실적을 바탕으로 기존학교건물의 비선형해석을 통한 내진성능평가를 하고 기둥내진보강방법을 제시하여 그 효과를 실험적으로 입증한 후 실제 학교구조물을 설계 예로 들어 내진보강설계에 적용하고자한다.
