Forward-Calculating Optimization Method for Determining the Rational Construction State of Cable-Stayed Bridges

Abstract:

In order to determine every rational construction state and obtain perfect finished dead state of the cable-stayed bridge, a quadratic programming model for optimizing cable tension was put forward. The adjustment of multi-object control parameters was achieved by using the weighting coefficient in the optimization model. In the optimization calculation of a cable-stayed bridge, the forward-calculating method was used and the results show that mechanics concept of this method is definite, the rate of convergence is fast and some disadvantages of other methods are avoided.
