Design of Added Dampers for Retrofit of Asymmetric Nonlinear Structures

비대칭$\cdot$비탄성구조물의 지진거동 개선을 위한 감쇠기 설계

In this study procedure for finding out additional viscous damping required to meet a performance target of an asymmetric nonlinear structure is developed based on the design concept of Pauly. The behavior of an asymmetric nonlinear structure after yielding is investigated. Finally the required amount of equivalent damping is obtained using the direct-displacement-based design method without carrying out time-consuming nonlinear dynamic time history analysis.
