In this paper the results of tests performed on specimens and structural el
ements made of steel fiber reinforced concrete (SFRC) are presented. Fiber
content of the concrete ranged from 0 to 60 kg/m(3). Using the results of t
he uniaxial compression tests performed under displacement control conditio
n, a stress-strain relationship for fiber concrete in compression was deriv
ed. Three-point bending tests on notched beams were carried out to simulate
the postcracking behavior and to evaluate the fracture energy. Based on th
e constitutive relationships derived from the experiments, a layered model
for the analysis of steel fiber reinforced concrete cross sections was deve
loped. The model performance and the benefits of fiber reinforcement on thi
n slabs reinforced with steel bars were assessed by carrying out rests on s
lab strips. The main results are presented and discussed.
