基于纤维模型的钢管混凝土拱桥结构非线性分析

纤维模型是近来引起广泛关注的构件非线性分析模型。文章介绍了纤维模型方法的计算原理,并采用OPENSEES中的纤维模型进行了应用。将纤维模型法应用于工程计算,并与试验法进行比较,结果表明,纤维模型方法可有效用于工程结构计算,为今后进一步应用奠定基础。

The fiber model is a component nonlinear analysis model that caused wide public concern recently. This paper in- troduces the calculation principle of fiber model method, and applying it in OPENSEES. The fiber model method is applied to en- gineering calculation, and compared with test method, the results show that the fiber model method can be effectively used in engineering structure, laying a foundation for further application.
