ABSTRACT
In this article the authors propose a numerical simulation method to investigate the influence of steel fibers on the creep property of fiber reinforced concrete (FRC). A finite element (FE) model of concrete structured with randomly distributed fibers is generated by using random numbers for fiber distribution and Delaunay triangulation for the triangular meshing, after slight modification of the location of fibers for better numerical results. The finite element model is prepared in 2-D as a plane stress problem. Through a number of numerical tests the results show that the randomness of fiber location influences the creep phenomenon within several percents of the one of regularly prepared fiber.
