超高層非免震建物群のモデル化およびRicker waveletに対する基本応答特性: パルス性地震動に対する大阪市域の超高層建物群の被害予測　その1

摘要

本論文では、大阪市域に立地する超高層建物群をモデル化し、パ ルス性地震動を単純化したRicker waveletに対する超高層建物群の応 答特性について検討した。得られた知見は以下の通りである。%The purpose of this study is to estimate the response and damage of existing super high-rise buildings in Osaka against strong pulse-like ground motions. In part1,a method of modeling super high-rise non-isolated buildings and a study of response properties for Ricker wavelet are described. It is confirmed that super high-rise buildings modeled by using 1st natural period described in published structural design documents might help grasping tendency and scale of regional damage. Also, aspects of damage might change completely different by the ratio of 1st natural period and pulse period of input wave T_1/T_P and pulse displacement D_p.
