超高層RC造建物の設計データベースに基づく振動解析モデルの構築とパルス性地震動入力に対する非線形応答特性の分析

抄録

This study investigates vibration analysis models of super high-rise RC buildings based on database for structural design and their nonlinear response characteristics to pulse-like ground motions. First, the applicability of multi-degree-of-freedom-system-model to pulse-like ground motions was verified. Next, the maximum inter-story drift angle and its occurrence position are described from nonlinear seismic response analysis for the Ricker wavelet input. Finally, we focus on the shift of the natural period due to the non-linearity of buildings for the pulse-like motion input.
