EVALUATION OF FUNDAMENTAL DYNAMIC CHARACTERISTICS AND SEISMIC RESPONSE CHARACTERISTICS OF HIGH-RISE DAMPED BUILDING WITH OIL DAMPER HAVING RELIEF LOAD

Abstract

We propose and validate an evaluation method for fundamental vibration characteristics of high-rise buildings considering the dynamic characteristics of oil dampers with relief load based on the theoretical background. In the evaluation method, we analyze the characteristics in the steady-state response of the system through the equivalent linearization method taking the effect of relief load into account. We validate the applicability of the proposed evaluation method by analyzing the fundamental vibration characteristics of a single-degree-of-freedom model, and investigate the applicability of to the seismic response evaluation of multi-degree-of-freedom model.
