Experimental studies of short concrete reinforced steel fiber beams under bending
2019
Revista IBRACON de Estruturas e Materiais
This paper presents the results of a test program on 24 concrete beams with a cross section of 15 x 15 cm. Those are divided into two groups of 12 beams. Group I has a steel fiber content of 40 kg/m³ while Group II uses 60 kg/m³ of steel fibers. The tests consider three sets of beam lengths: 300 mm, 500 mm and 800 mm. The beams were submitted to bending aiming at investigating shear stresses, bending, strain energy, toughness, scale effect and fracture energy. Group II showed a slightly higher
