基于随机反应谱的结构动力可靠性分析
|
摘要
基于随机振动理论,详细介绍了随机反应谱的生成过程,并将随机反应谱应用于结构动力可靠性的分析;对于结构动力响应量则采用了级数拟合法,使得动力可靠性分析问题转化为拟合结构响应的静力可靠度问题,从而为结构动力可靠度的计算提供了一种实用方法。
Based on the random vibration theory, the generated process of the random response spectra is particularly presented and the random response spectra to the structure dynamic reliability analysis is also applied; as for the structure dynamic response quantum, the series fitting is adopted which made the problem of dynamic reliability analysis be transformed to the one of static force reliability of the fitting structure response. Thus, it offers a practice method to the calculation of the structure dynamic reliability.
