基于贝叶斯理论的随机风荷载作用下悬索桥颤振可靠性分析
Reliability Analysis of Suspension Bridge Flutter under Stochastic Wind Loading Based on Bayesian Theory
摘要
Abstract
To analyze the reliability of suspension bridge flutter under stochastic wind loading, this paper established the model being suitable for analyzing the flutter of long-span suspension bridge flutter based on the method of forecasting extreme air speed in the Bayesian theory. In the course of establishing the limit state equation, flutter critical wind speed, conversion factor, gust factor and extreme wind speed at the bridge site were selected as elementary random variables, JC method in linear order second moment based on FERUM was used to calculate the flutter reliability indices of the long-span suspension bridge.The results indicated that this method was more precise and objective than traditional one and had high value in application to practical engineering.关键词
