Research on Setting of Pre-Camber of Long-Span Continuous Rigid Frame Bridge with High Piers

Abstract:

In the design of continuous rigid frame bridge setting reasonable pre-camber can eliminate the impact of various loads on the linear in construction process, reduce shrinkage and creep in the process of post-operation, the late loss of pre-stressed, deformation produced by live load and so on ,resulting in deflection phenomenon. Based on the current specifications of the continuous rigid frame bridge camber setting methods, this thesis proposes the reasonable setting suggestions of pre-camber and sets examples to illustrate this.
