Launching of steel bridge girder. Application of nonlinear shell models
The paper describes the final technology of launching the steel bridge superstructure. The original technology failed in the first construction stage. Local damage of steel webs caused by plastic buckling stopped the procedure. In the effect of damage a new consulting team was employed to solve the problem and redesign a technology of constructing. The key element of the new solution was developed with great help of non-linear shell FEM model of a span. The paper presents construction methods, applied theoretical analysis and a number of conclusions resulting from the collected experience.
