Development and Nonlinear Dynamic Model of Sliding Wall Damper To Retrofit of R/C Frame Structures

R/C 골조구조물 내진보강을 위한 슬라이딩 벽식감쇠기의 개발 및 비선형 동적해석모델

In order to retrofit R/C frame structures, a newly proposed Teflon sliding wall damper, consisted of Teflon slider and R/C shear wall, is evaluated by the dynamic analysis model of inelastic frame structures. From analysis results, it is shown that the damper reduces the time-history responses, the maximum story drifts, and the damage of R/C member. By control of damper pressures, especially, the damper can be easily applicable not only to capacity design according to required responses and member damages but also to active damper with actively controlling devices.
