Full-Scale Model Test and Numerical Modelling for Behaviour of Saddle Segment of a Extradosed Bridge

Abstract:

Najin Bridge, located in Lasa of China, is an extradosed bridge with three towers and with the (70+117+117+70)m spans. The turning radius of all saddle in the main tower of this bridge is 2.5 m. Now minimum radius of the saddle at extradosed bridges in China is 2.8m. For the security and reliability of the bridge, we researched and analyzed the stress of saddle segment by the ANSYS software accurately, and carried on the full-scale model test. Some suggestions are proposed for this bridge.
