2016년 9월 경주지진, 2017년 11월 발생한 포항지진 이후 공공시설중 상대적으로 내진성능 보급이 부진하였던 학교시설의 경우 2017년~2019년 사이 2배 이상 보급되었다. 내진보강공사가 공급됨으로 늘어난 비중에 하자가 발생할 가능성이 존재한다. 정부는 오는 2035년까지 모든 공공시설에 내진성능보강공사를 완료하고 학교시설의 경우 2029년까지 내진성능보급을 완료하는 것으로 확인되었다. 이에 따라 선행연구를 고찰해보았고 학교시설공사에서 발생하는 하자에 관련한 연구가 진행되는 것으로 확인되었다. 하지만 마감공사에서 발생하는 하자 예방에 대한 연구가 진행되고 있었으며, 학교시설의 내진보강공사에서 발생하는 하자에 관련한 연구는 부족한 실정이었다. 따라서 본 연구는 내진보강공사에서 발생하는 하자 유형들을 조사하고 해당 원인들을 분석하여 하자예방의 중점관리요소를 도출할 것이다. 또한 궁극적으로 하자 유형과 원인간의 관계를 분석하여 중점관리요소를 선정함으로써 향후 내진보강공사를 진행함에 있어 시공단계에서 하자를 예방할 수 있고, 보수비용을 저감하는데 기여할 것이다.

Abstract ▼ AI-Helper

This research addresses the types and causes of defects in seismic retrofitting projects of school facilities, which, following the Gyeongju and Pohang earthquakes in September 2016 and November 2017 respectively, have been identified as having comparatively lower seismic resilience among public buildings. The incidence of seismic retrofitting has notably increased in the subsequent years, raising concerns about the potential for defects arising from these efforts. The government has committed to enhancing the seismic resilience of all public facilities by 2035, with a specific focus on completing upgrades for educational establishments by 2029. Although prior investigations have explored construction defects in school facilities, there exists a gap in research specifically targeting defects within seismic retrofitting processes. Thus, this study aims to catalog the defects associated with seismic retrofitting efforts and analyze their underlying causes to identify crucial management strategies for defect mitigation. Furthermore, by examining the interplay between defect types and their causative factors, the study seeks to pinpoint essential management practices that could preempt defects during the construction phase, ultimately aiding in the reduction of future maintenance expenditures.
