초록
본 연구는 우리나라에서 가장 일반적인 중소규모의 비내진 상세를 가진 건축물을 대상으로, 노후도를 고려하여 내진성능을 평가하였다. 평가결과, 준공 후 24년이 경과되었으나 노후도는 대체로 양호한 것으로 평가되었고, 1차, 2차 내진성능평가는 기준지표를 만족하지 못하는 것으로 나타났다. 3차 내진성능평가에서는 층간변위비를 기준으로 목표성능은 만족하지만 보강이 필요한것으로 판단되었다. 대상 건축물에 벽체보강, 가새보강, 댐퍼보강을 한 후 내진성능평가를 실시한 결과, 보강방법에 상관없이 층간변위비는 현저히 감소하여 즉시거주수준을 만족하는 수준으로 나타났다. 그러나 벽체보강의 경우 밑면전단력이 2배 이상 증가되어 기존기초에 대한 검토가 필요하다.
Abstract
In this study, seismic performance was evaluated considering the deterioration level for the low-rise and moderate buildings with non-seismic details which are most common in Korea. Evaluation results showed that the deterioration condition is relatively good even after 24 years of construction but the seismic performance did not satisfy the protection index in the first and second evaluation. In case of the third evaluation, the goal performance was satisfied based on the interstory drift ratio but reinforcement is found to be necessary. Seismic performance was evaluated after the target buildings were reinforced in the walls, bracing, and damper. Results showed the interstory drift ratio drastically reduced regardless of reinforcement methods and satisfied the level of immediate occupancy. In case of wall reinforcement,however, base shear increased more than double which requires review on the existing foundation.
