Based upon the theory of determining rational bridging status of cable stayed bridges of ternary components,this paper puts forward the idea of determining rational bridging cable force for self-anchorage suspension bridges by rigid support continuous beam method and min.

Precise calculation of proper buckling force is needed in the multi-segment hoisting method t o make sure that the structural stress and g eometry under bridge complete stage can meet the requirements.

PVDF Sensors Used for on Line Measurement of Stayed Cable Tension of Cable-stayed Bridges;

Deciding the reasonable finished dead state of the main beam of Cable-stayed bridges using stress balanced method;

In this paper, a concept of reasonable finished dead state of cable-stayed bridges and existing methods of cable tension optimization for cable-stayed bridges are firstly introduced.

The step by step arithmetic for the reasonable finished dead state of the concrete cable stayed bridges is proposed on basis of minimum bending energy method, influence matrix method and stress balancing method.
