Inelastic Behavior of Reinforced Fibrous Concrete
Publication: Journal of Structural Engineering
Volume 113, Issue 4
Abstract
This paper discusses the increased ductility afforded conventional reinforced concrete sections through the inclusion of deformed steel fibers. Computation of the theoretical moment‐rotation relationship was done for all sections, using a computer program developed for this study. In order to show that the behavior of the reinforced fibrous concrete beam computed by the program is correct, four full‐sized beams were tested at the New Jersey Institute of Technology and compared to the theoretical development. Various factors affecting the section behavior are evaluated. These variables are: (1) Material variables: concrete, grades of tension and compression reinforcing, fibers, and strain‐hardening of steel; and (2) geometric variables: amount of tension reinforcement, amount of compression reinforcement, and amount of fiber. The conclusions on the effects of the fibers on the ductility of the conventional reinforced concrete sections are summarized.
