Paper Title:
The Clever Use of Neutron-Axis of the Girder in the Stress Measurement of the Large Span PC Cable Stayed Bridge
  Abstract

As the stress measurement of interior concrete is hard in the construction control of the cable- stayed bridge, a new method fitted for stress measurement in large span PC concrete cable-stayed bridge is proposed in this paper. This method is based on the principle that the normal stress in neutron-axis of girder is only decided by the horizontal part of the cable force. First, the normal stress on the neutron-axis of girder is calculated by the measured cable force, and then the creep coefficient is identified, and finally the other stresses are worked out. This method has been applied to a large span PC cable-stayed bridge constructed in process with favourable results and thus proves its accuracy and efficiency.
