Abstract

A procedure is presented for determining stresses and strains in reinforced concrete sections with or without prestressing. Cross sections of arbitrary shape are considered and the immediate and long term  stresses and strains are evaluated, accounting for the effects of creep and shrinkage of concrete and relaxation of prestressed steel. A numerical example is included to show how the proposed method can be  applied.
