Abstract
The cable anchorage region in a girder is the key part of cable stayed bridge， in which stress distribution is rather complicated. A general plane analysis method is hard to reflect actual stress status. According to the design of Fengdu Second Yangtze River Bridge In this paper, the analysis of the spatial stress distribution of the cable anchorage structure in a girder is carried out in design load by making use of the common analysis software-Midas FEA and spatial finite element method, the verification and assessment of Fengdu Second Yangtze River Bridge Anchor Plate rational structural design is conducted, in order to put forward optimize the design suggestions, to ensure that such structures the realization of economy and reliability.
