Open publisher page 0 citations

Abstract

The pylon of Lanshu bridge is curved and has continually varying section.The pylon is skew on the main span,which is different to that of general cable-stayed bridge.Prestressing strands are laid in the pylon and the constitution of anchorage zone is complicate.So ANSYS finite element program is used to analyze its stresses.The results show that the pylon stresses can meet the code requirement.The calculation method and the conclusions can be referenced to mechanic analysis of the same type pylon of cable-stayed bridge.
