Abstract

The main objective of this paper is to evaluate the control performance of a coulomb friction damper(CFD) for controlling the inelastic behavior of seismically excited structures, The seismic performances of various buildings are evaluated using capacity spectrum method(CSM), and the additional dampings are calculated If the evaluated performance levels of the buildings are below the target level. Maximum friction force of the CFD to achieve additional damping is provided using the concept of equivalent viscous damping, Numerical simulations for single degree of freedom(SDOF) systems with various structural periods and post yield stiffness ratios demonstrate the effectiveness of the proposed procedure.

이 논문의 주된 목적은 지진을 받는 구조물의 비탄성 거동을 제어하기 위해 Coulomb 마찰감쇠기의 제어성능을 산출하는 것이다. 능력스펙트럼법을 이용하여 다양한 건물의 내진성능이 평가되나, 만약 평가된 성능수준이 목표수준에 미치지 못할 때는 추가적인 감쇠비를 산출하게 된다. 추가적인 감쇠비를 얻기 위한 마찰감쇠기의 리더 마찰력은 등가 점성 감쇠의 개념을 사용하여 산정된다. 이와 같이 제안된 방법의 효과를 증명하기 위해, 다양한 주기와 항복 후 강성비를 가진 단자유도 구조물들에 대하여 수치해석을 수행하였다.
