High-Strength Concrete: SP1 - Beams and Columns. Report 1.6. Ductility of Overreinforced Beams
The report presents the experimental results from test of 11 overreinforced high strength concrete beams, with depth 550 mm and length 4,500 mm. The variables considered were the amount and the distribution of stirrup reinforcement. Three different concrete qualities were used, two of normal density aggregate (cylinder strength at 28 days; 69 MPa and 91 MPa, respectively) and one of lightweight aggregate (62 MPa). It is documented that it is possible to obtain a ductile behavior even with the lowest stirrup ratio of 0.6%. The load capacity was maintained after the detachment of the concrete cover and the deflection increased up to 70%. Numerical simulations with the FCB model for confined concrete columns verified its applicability also to overreinforced beams.
