摘要
提出了可用于三维地震动相关性分析的四段连续型强度包线函数模型及其估计方法 ,对三维地震动强度非平稳特性的相关性进行了统计分析并给出其设计取值建议。
A model of intensity envelope function is improved to be a four segment one which can be used to deal with the correlation of 3 D ground motion components, and a method to estimate the model parameters is proposed. The correlativity of the parameters of 3 D ground motion components is studied and the values of parameters considering the correlativity are suggested accordingly.
