【Abstract】 Based on the theory of finite-element,the calculations were made on some skew girder bridge by the large-scale finite element analysis software.Some regularities of distribution of the stress and the dynamic characteristics were concluded after comparing the mechanics characteristics of the skew girder bridge and the orthogonal bridge.The conclusion of research could be used to provide important reference for the design of the similar type of bridge in future.更多还原
