Model Test of Prestressed Tension Sequence for Curved Girder Bridge

摘要：

The prestrssed curved girder model with 1:20 scale was designed and manufactured, and the effect of prestressed tension sequence on the strain of the structure was analyzed by model test and finite element method. Steel wire ropes with 1.4mm diameter are used to simulate prestressed steel wires of actual bridge, the total steel wire ropes are divided into six groups, each group consists of two steel wires.The static strain measurement system is used for the data acquisition and analysis. The optimum sequence of prestressed tension is given.
