Finite element analysis of reinforced concrete beams
ACI Journal Proceedings, 64, ACI, (1967)
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.
