摘要：
Base-isolation system is designed to lengthen the period of the building. However, this can also increase wind-induced responses of the structure since wind forces have long duration and predominant energy on long periods. Furthermore, the mean component in the along-wind direction also causes certain base-isolation components, such as sliding bearings to become prone to creep phenomenon. Despite of this, evaluation methods of wind-induced response considering creep property on highrise base-isolated buildings with sliding bearings has not yet been fully investigated. Therefore, this paper examines the evaluation method on those buildings and clarifies the effect of creep property using time-history analysis. © 2022 Architectural Institute of Japan.
