Deformational analysis of prestressed high strength concrete members by different methods

Abstract

In this paper, an attempt has been made to extend application of the recently proposed Flexural constitutive model to short- and long-term deformational analysis of flexural partially prestressed concrete members. The proposed calculation technique is applied in a simple engineering technique based on principles of strength of materials and the layered approach. The effect of tension stiffening and non-linear time effects of creep and shrinkage are taken into account. Effective modulus method is used for modeling of long-term deformations. Shortand long-term deformation (curvatures) prediction results were tested against experimental data of partially prestressed concrete beams reported in the literature.
