Arch Bridge Tower Design and Temperature Gradient Effect of Its Concrete Plan

Guangzhou Liede Bridge is a long-span bridge in the project of Xinguang Express Road.Its highlight lies in its particular design of the bridge tower.The figuration of the tower is made up of two shells.In its design,three styles for the tower are contrasted: concrete tower,steel-truss tower and steel-box tower.The project regulates the saddle position of the concrete tower bridge,its concrete,steel shell and its height of crossbeam,discusses its tower force and displacement,and applies some of the valuable results to the project design.Many countries regulate their specifications in calculating bridge temperature stress in detail,but they do not specify how to calculate the temperature stress of a no-beam construction like a bridge pier or tower.This paper compares different specifications,and according to the specifications selected,analyzes the temperature stress of the concrete tower by employing FEA method and 3D solid element.
