Abstract
Fiber reinforced concrete usage has steadily increased over the past 20 years. The objective is to evaluate the bond characteristics of a bar embedded in plain and fiber reinforced concrete. Nonlinear finite element analysis is used to analyze the pullout mechanism for reinforcing bars embedded in concrete. Cracking behavior, bond strength, and type of failure are obtained analytically, and compared with experimental results, and concrete stresses around the bar are estimated. The results show that finite element method can be used to predict accurately the bond mechanism for both plain and fiber reinforced concrete.
