随着高速公路的大规模修建,特别是城市立交桥建设的需要,弯梁桥结构在我国已被广泛采用。近年来,由于计算机的快速发展,用微分方程的数值解法对工程结构进行分析计算的方法越来越趋于成熟,运用结构分析的数值方法在增加多因素的情况下,仍可以解决许多复杂的问题。从而使对于构件非线性问题的探索达到一个全新的层面,本文就是基于曲线梁桥的自身特点,对其研究方法加以概述。
With the large-scale construction of expressways, especially the construction of urban overpasses, the curved beam bridge structure has been widely adopted in our country. In recent years, due to the rapid development of computers, the numerical methods of differential equations are becoming more and more mature. The numerical methods of structural analysis can still solve many complicated problems with the increase of multi-factors problem. So that to explore a new dimension for the nonlinear problem of components, this article is based on the characteristics of curved girder bridge, and its research methods are summarized.
