Abstract:
A series of compression tests were conducted on 3 x 6-in. cylindrical specimens using a modified test method that gave the complete stress-strain behavior for high-strength steel-fiber concrete with or without tie confinements. The volume fractions of steel fiber in the concrete were 0, 0.5, 0.75, and 1 percent, respectively. Empirical equations are proposed herein to represent the complete stress-strain relationships of high-strength steel-fiber concrete with compressive strength exceeding 10,000 psi. Various parameters were studied, and their relationships were experimentally determined. The proposed empirical stress-strain equations have been compared to actual cylinder tests under axial compression and were found to be in good agreement.
