Fiber Reinforced High-Performance Concrete Beams Material and Structural Behavior
The mechanical behavior of a few plain and fiber-reinforced high-performance concretes 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. Then the overall behavior of two P/C beams typifying the sub-elements of a hollow-core slab is examined, with and without fibers to study crack formation and propagation (by optical interferometry) and structural ductility.
