Abstract

In this study, a seismic reinforcement system was developed considering the rocking behavior of walls. The rocking behavior is to rotate left and right around the vertical axis of the wall, and the development system is a method of dissipating energy by installing a damper to a large displacement part. Developed steel rod damper was used, and steel rod diameter and length(aspect ratio) were selected as variables. As a result of the experiment, it was evaluated to have excellent seismic performance when the damper length was 260mm.

본 연구에서는 벽체의 록킹 거동을 고려한 내진보강 기법을 개발하였다. 록킹 거동은 벽체 수직 축을 중심으로 좌우로 회전하는 것으로, 개발 시스템은 변위 큰 부분에 댐퍼 등을 설치하여 에너지를 소산 시키는 방법이다. 댐퍼는 강봉 댐퍼를 사용하였으며, 강봉 지름 및 길이(형상비)를 변수로 선정하였다. 실험결과 댐퍼길이 260mm 경우 우수한 내진 성능을 보유한 것으로 평가되었다.
