Using SDA Model in the Designing Process of Fiber-Reinforced Concrete Beams
Publication: Journal of Materials in Civil Engineering
Volume 33, Issue 8
Abstract
Fiber-reinforced concrete (FRC) structures are mainly designed using finite-element software. The input parameters used in these methods are based on the material properties of FRC obtained from test results. Because the experimental results of FRC show huge deviations, the material properties determined by an ordinary number of experiments do not give a realistic average value. This work aims to determine the real expected value and deviation of material properties using a semidiscrete analytical (SDA) model (using the average value and deviation of the fiber distribution and the minor deviation parameters of the SDA model). The input parameters of the design software can be determined much more accurately with these results. Finally, the number of experiments obtained can be decreased, and the advantage of adding fibers to the concrete can be effectively achieved.
