Study on the Performance of Prestressed Concrete Beams Reinforced with Steel Fibers (HPRF)
Journal: Journal of Building Technology DOI: 10.32629/jbt.v6i2.2742
Abstract
The addition of fibers to concrete improves the shear performance of a structural element. However, there is a greater amount of scientific work on the evaluation of the effects of fibers in reinforced concrete structural elements than in prestressed elements. In this work, the behavior of HPRF beams tested in shear by other researchers is studied numerically in order to evaluate the contribution of fibers. The objective is to contribute to the efficient design of this type of beams. For this purpose, a shear test is modeled and the parameters of the constitutive model are calibrated by comparing the numerical results with the experimental ones. Then, the numerical model is used to reproduce the behavior of an experimentally tested HPRF beam.
