两种数值计算方法在桥梁结构计算上的应用

The application of two numerical methods in the bridge structure calculation

从力学问题出发来介绍计算力学中流行的两类方法:有限元法及加权参数法并以比较,同时介绍其前身Rayleigh-Ritz法与Galerkin法,并给出算例对这两种方法进行比较,具有一定的参考价值。

The paper started with mechanics problems, two popular calculation methods in mechanics were introduced and compared, which were finite element method and weighting parameter method. Their precursor Rayleigh-Ritz method and Galerkin method were introduced, the calculation example and comparison of two methods were presented, which had some reference value.
