초록
본 연구에서는 벽식 아파트 RC 연결보 성능을 증진시키기 위하여, 강봉댐퍼를 연결보에 적용하였다, 실험 변수는 강봉의 개수이며, 총 4개의 실험체를 제작하였다. 강봉의 재료시험결과, KS 규격에 적합한 것으로 평가되었다. 실험 결과, 강봉과 연결부의 용접부위가 아닌 강봉에 응력이 집중되는 것으로 평가되었다. 최대강도는 강봉댐퍼 개수 증가에 따라 비례적으로 증가하지는 않지만 선형적으로 증가하는 것으로 평가되었다.
Abstract
In this study, in order to improve the performance of wall-type apartment RC coupling beams, a steel rod damper was applied to the coupling beams. The test variable was the number of steel rods, and a total of 4 test specimens were made. As a result of the material test of the steel rod, it was evaluated as conforming to KS standards. As a result of the test, it was evaluated that the stress was concentrated in the steel rod and not in the welded area of the steel rod and connection plate. The maximum strength was evaluated to increase linearly, but not proportionally, as the number of steel rod dampers increased.
