초록
본 연구에서는 강봉댐퍼의 변위의존성 평가, 강도 및 에너지소산능력을 평가하였다. 실험 변수는 단면형상 및 형상비이며, 총 6개의 실험체를 제작하였다. 실험 결과, 설계기준에서 제시한 변위 의존성 조건을 모든 실험체가 만족하는 것으로 평가되었다. 그리고 단면형상에따른 강도 영향은 미비하였다. 결과적으로, 형상비 13.7의 강도 및 에너지소산능력이 우수한 것으로 평가되었다.
Abstract
In this study, the displacement dependence, strength, and energy dissipation capacity of the steel rod damper were evaluated. The test variables were cross-sectional shape and aspect ratio. The 6th test specimens were made for performance test. From the test results, it was evaluated that the displacement dependence conditions of design code were satisfied in all specimens. And the strength effect according to the cross-sectional shape was minimal. As a result, the strength and energy dissipation capacity of the aspect ratio of 13.7 were evaluated as excellent.
