ABSTRACT

Methods of analysis to evaluate the short-and long-term response of concrete crosssections subjected to axial force and biaxial bending are presented in this chapter. These methods are particularly useful for the analysis of reinforced, prestressed or composite steel-concrete columns in building structures. The concrete is assumed to remain uncracked and be able to carry any applied tension. The proposed formulation relies on the Euler-Bernoulli beam assumptions which require plane sections to remain plane and perpendicular to the member axis before and after deformation.
