기존 비내진상세를 가지는 철근콘크리트 학교건물의 입면미관을 고려한 강재댐퍼 내진보강법의 보강효과

초록

The 2017 Pohang earthquake caused serious earthquake damage to newly constructed piloti and apartments, including school facilities. In particular, the shear failure of reinforced concrete (R/C) school buildings, which lacked shear reinforcement, has been highlighted as an important issue for future earthquake countermeasures in Korea. Against this background, the seismic strengthening project, including seismic control device (damper), has been actively conducted in school buildings since 2018. However, it is common for schools to not consider the aesthetic elements of their facade in these seismic strengthening project. The purpose of this study is to deriv e the optimal shape of the steel damper seismic retrofitting method considering the facade aesthetics of existing R/C school buildings having non-seismic details. First of all, a survey of 111 people, including experts, architectural college students, and faculty members, conducted a survey to investigate the preference of the steel damper seismic reinforcement method for facade aesthetics. Finally, each steel damper seismic reinforcement method, which is a result of the preference survey, was applied to the target building to conduct a three-dimensional nonlinear dy namic analysis to evaluate the seismic reinforcement effect.
