Abstract:
The basic concept of using the finite element method of analysis in constructing an analytical model for the study of the behavior of reinforced concrete members is discussed. The finite elements chosen to represent the concrete, the steel reinforcement, and the bond links between the concrete and the steel reinforcement are described. Several examples of singly reinforced concrete beams on simple supports with different idealized cracking patterns are analyzed and re-sults are presented for comparison and discussion. The effect of the assumed stiffness of the bond links is also exam-ined briefly. No general conclusions regarding the behavior of the reinforced concrete beams under load are attempted in the present investigation. The purpose of the paper is to demonstrate the feasibility and to explore the potentialities as well as the difficulties of using the finite element method, with an ultimate aim of developing a general analytical method for the study of reinforced concrete members in the full range of loading.
