摘要
本文使用传统的目标函数最小化方法,对结构最大反应的真实概率分布进行曲线拟合,旨在探索结构最大反应的真实概率分布形式.为了便于数据对比,本研究将结构最大反应拟合为正态分布的形式,并对曲线拟合和直接计算得到的地震动反应谱进行对比分析.结果表明,曲线拟合得到的分布函数更能真实反应地震动反应谱的统计规律.
Using the traditional objective function minimization method, the paper makes curve fitting of real probability distribution of maximum response to the real probability distribution of the maximum response. In or-der to explore he probability distribution of the maximum structure reaction and facilitate the data comparison, the paper compares and analyzes the structure of the maximum response form fitting for the normal distribution, the spectral analysis response curve fitting and direct calculation of the sesismic response spectrum. The results show that the distribution function curve fitting can truly reflect seismic statistical regularity of response spectrum.
