Title: Fiber Reinforced High-Performance Concrete Beams Material and Structural Behavior
Author(s): M. Marazzini and G. Rosati
Publication: Special Publication
Appears on pages(s): 29-52
Keywords: bond; concretes; cracking; hollow-core slabs; steel fibers; structural ductility; tensile behavior; test methods (concrete)
Abstract:The mechanical behavior of a few plain and fiber-reinforced high performance concretes (fact=80-130 Mpa) is studied here by means of direct tensile tests and three-point bending tests, and a special "identification" Procedure is adopted in order to cleanse the stress-strain and stress-displacement curves of any undesired structural effect. The overall behavior of two P/C beams typifying the sub-elements of a hollow-core slab is examined, with and without fibers, to sturdy crack formation and propagation ( by optical interferometry) and structural ductility.
