Abstract

The finite strip method has successfully introduced in the study of viscoelastic behaviour of prestressed concrete girders. The reason for the introduction of this method lies in the fact that resolving of several classes of practical problems it is much faster than the more comprehensive and adaptable finite element method. This is generally valid for structures with regular geometrical shape and simple boundary conditions, whose discretization into many finite elements is often very expensive. In such cases the finite strip method can be extremely competitive in terms of cost and accuracy, both during computations and in practical application. Discretization of the cross-section into a mesh of only several finite strips enables the solution of complex structural problems.
