摘要:
采用主成分分析法与混沌时间序列分析方法对地震动的非线性特性进行分析,分别从定性与定量的角度考察地震动的非线性特性;探讨了地震动的要素对其混沌特性的影响。结果表明:地震动最大幅值的变化对混沌特性没有影响,而持时、频谱特性、采样频率等要素对混沌的定量指标均产生了影响。
Abstract:
The principal component analysis and chaotic time series analysis methods were applied to analyze the ground motion’s nonlinear characteristics, which were investigated from both the qualitative and quantitative perspectives. The influence of the key elements of the ground motion on its chaotic characteristics was discussed. Results show that the change of the maximum value of ground motion has no effect on the chaotic characteristics. Such key elements as the duration, spectrum characteristics, sampling frequency and so on have impacts on the quantitative indicators of the chaos.
