Abstract
The seismic performance of anchored brick veneer with a newly developed tie metal assembly in the nonstructural masonry wall was evaluated experimentally in this study. The test specimens were manufactured with dimensions of 2.2 m × 2.02 m. The experimental variables were the arrangement of the tie metal assembly (orthogonal or staggered), the spacing of the tie metal assembly, and the size of the vertical locking bars. All the test specimens with tie metal assemblies were capable of supporting the equivalent static load based on the Korean Building Code, and retained a drift capacity of more than 2% corresponding to the performance level of life safety. The vertical locking bars improve the seismic performance of anchored brick veneer moderately, and the recommended spacing of the tie metal assembly is 800 mm × 400 mm.

요지
이 연구에서는 건축물의 외장재로 널리 사용되는 외벽조적벽체에서 새롭게 개발된 연결철물 상세에 대한 내진성능을 실험적으로 평가하였다. 실험체의 크기는 2.2 m × 2.02 m이고, 주요 실험변수로는 연결철물의 배치방법(정렬배치, 엇모배치)과 연결철물의 보강간격 및 수직 록킹 바의 크기이다. 실험결과 연결철물을 설치한 모든 실험체가 국내건축기준에 의한 등가정적횡하중 이상을 지지할 수 있으며, 2% 이상의 횡변위각 성능을 발휘하여 인명안전의 성능수준을 만족하고 있음을 확인하였다. 또한 수직 록킹 바는 외벽조적벽체의 내진성능을 향상시키며, 연결철물의 간격은 800 mm × 400 mm으로 하는 것이 바람직하다.
