내진성능보강을 위한 능력스펙트럼법을 이용한 마찰감쇠기 설계 = Design of Friction Dampers to Improve Seismic Performance Using Capacity Spectrum Method

다국어 초록 (Multilingual Abstract)

The main objective of this paper is to propose a retrofitting method using Coulomb friction dampers. The seismic performance of an existing building is evaluated, and an additional necessary damping is calculated using capacity spectrum method(CSM) if the evaluated performance level of the building is below the target level. The coefficients of the Coulomb friction damper are then calculated using the proposed formula, which is derived from the concept of hysteresis loop. Numerical simulations are made to demonstrate the effectiveness of the proposed method.
