| Abstract: | With reference to the calculations of three-dimensional solid finite element of the composite pylon of Shanghai Changjiang River Bridge,a simplified method is proposed for calculating steel and concrete composite pylon subjected to loads transverse and vertical to bridge and the calculations by the method are compared to those of the three-dimensional finite element. The method as mentioned herewith is of fairly high calculation accuracy and can be used for calculation in the bridge design of similar kind. |
