Research of Calculation Methods for Zero Block of Continuous Beam and Continuous Rigid Frame Bridges
In order to optimize the zero block analysis method of continuous beam and continuous rigid frame bridge and provide better service for zero block design, a research for size of geometric model, pre-stressing simulation method, loading method and boundary conditions simulation was made. Some useful approaches for zero block calculation were presented through a lot of variable parameter analysis. A method considering the effect of reinforcement ratio was suggested to further judge calculation results of zero block three-dimensional finite element model (FEM). The results showed that the recommended zero block optimal calculation method has high practical value.
