Abstract

Although friction pendulum system has various advantages it is difficult to estimate the behavior because of velocity, bearing pressure, and temperature dependent characteristics of coefficient of friction. This research focuses on evaluating the conservatism of each method used and the effects of bearing pressure on the behavior of the system by conducting comprehensive examination on design and analytic procedure of friction pendulum system, as is proposed in standard, code and literature. In addition, this study provides comparative analysis on general behavior characteristics of friction pendulum system by comparing the result with that of the analysis on lead rubber bearing which possesses the same dynamic properties.

마찰진자형 면진받침은 마찰면의 곡률반경과 중력에 의해 생성되는 고유 복원력과 마찰에 의한 감쇠력을 갖는다는 장점이 있지만, 마찰계수의 속도, 상재압 및 온도 등에 대한 의존성으로 거동에 대한 예측이 쉽지 않다. 본 연구에서는 각 기준에서 제시된 마찰진자형 받침의 설계 및 해석절차를 분석하여 추가적인 검토가 필요한 사항들에 대해 평가해 보았으며, 추가로 동일한 동특성을 갖는 납-고무 면진받침 시스템을 이용한 해석결과와 마찰진자형 면진받침 시스템의 해석결과를 비교하여 마찰진자형 면진받침이 갖는 상대적인 거동 특성을 비교 분석해 보았다.
