In this paper, an analytical method for short and long term analysis of steel-concrete continuous composite girders with fractionated slab castings is proposed by taking into account the flexibility of the shear connection and the concrete behavior at early ages (concrete autogenous shrinkage and hydration thermal strain). The numerical solution is achieved by means of a finite element approach in conjunction with the step-by-step procedures. The proposed method is applied to a four span continuous composite deck by analyzing the tensile stresses in the slab produced by two different casting sequences.

Abstract
In this paper, an analytical method for short and long term analysis of steel-concrete continuous composite girders with fractionated slab castings is proposed by taking into account the flexibility of the shear connection and the concrete behavior at early ages (concrete autogenous shrinkage and hydration thermal strain). The numerical solution is achieved by means of a finite element approach in conjunction with the step-by-step procedures. The proposed method is applied to a four span continuous composite deck by analyzing the tensile stresses in the slab produced by two different casting sequences.File in questo prodotto:
