Popis:	Presented in this paper is a study on the creep and relaxation behavior of the composite girders with the precast prestressed concrete slabs using a simple linear visco-elastic model for the concrete slab and by making use of the Laplace and its numerical inverse transforms in view of the principle of correspondence to the linear elasticity.The comparison of the analytical results with those of long-term experiments on precast prestressed slabs and composite girders specifically scheduled and conducted by the authors have shown that upon determination of the visco-elastic constants from the prestressed concrete slab tests, the creep and relaxation behavior of the precast prestressed composite girders presented herein can be reasonably well predicted by a simple linear visco-elastic model.
