VALIDATION OF PEAK FACTOR PROPOSED BY JAPANESE DESIGN CODE IN ESTIMATION MAXIMUM RESPONSE AND CONTROL FORCE FOR HIGH-RISE BASE-ISOLATED BUILDING SUBJECTED TO ACROSS-WIND FORCE

Abstract

In recent years, the combination of base isolation and active structural control (active base isolation) has been extensively studied. Conventional design approaches for control systems rely on trial-and-error methods and numerical simulations, which are time-consuming. To propose a simple design method for active base isolations, this paper validates the effectiveness of the peak factor from the Japanese design code in estimating the maximum response and maximum control force as the first stage. We considered different superstructure heights, isolation natural periods, and numbers of hysteretic dampers for validations. Numerical results indicate that the peak factor proposed by Japanese design code accurately estimates the maximum control force in all cases. However, it can only be used to estimate the maximum response for active base isolations within the elastic range.
