基于斜交异性板单元的斜桥有限元分析

Skew Bridge Finite Element Analysis Based on Skew Anisotropic Element

通过推导一种新型的斜桥分析单元──斜交异性板单元，实现了斜桥的空间有限元分析；通过与实用计算方法的对比，证明了这一方法的可靠性；最后，应用这一方法，结合工程实例介绍了斜桥影响面生成。

Space finite element analysis of skew bridge is realized via the derivation of a new finite element-skew anisotropic element. The reliability of the method is verified by comparison with the popular methed. Finally, skew bridge influential surface generation,influential surface loading as well as skew bridge reinforcement calculation are discussed with the introduction of an example of skew bridge.
