Title: Theoretical Model for Confined Steel-Fiber-Reinforced High-Strength Concrete
Author(s): H.C. Lima, Jr. and J.S. Giongo
Publication: Special Publication
Appears on pages(s): 273-286
Keywords: confinement; high strength concrete; mathematical model; steel fiber
Abstract:A theoretical model for steel-fiber-reinforced high strength concrete was developed and calibrated against the test results from 86 high-strength concrete columns tested under axial load. The effects of steel-fibers, the concrete compressive strength, and the transverse and longitudinal reinforcement ratio were accounted for in the proposed stress-strain model. The current model is based on the model developed by Cusson and Paultre, in which the effect of steel-fibers on the concrete ductility was incorporated using the reinforcement index of the volumetric ratio of the steel-fiber addition. The agreement between the model responses and test results was satisfactory.
