Model Tests and Comparative Study of the Pylon's Anchorage Zone of Two Long-span Cablae-stayed Bridges

PC Structures

Abstract

Two model tests for pylon's anchorage zone of two long span cable stayed bridges, the Second Nanjing Yangtze River Bridge and the Runyang Yangtze River Bridge, are expounded in this paper. Safety factors for cracking and ultimate strength are obtained. The optimal configuration of prestress tendons in anchorage zone, and the emulation effects of segment model test to integral pylon are investigated. The results can be a reference for the design of pylon of cable stayed bridges.
