Nonlinear Finite Element Analysis of High Strength Fiber Reinforced Concrete Corbels


This research work presents a nonlinear fini te elementinvestigation on the behavior of high strength fiber reinforced concretecorbels. This investigation is carried out in order to get a betterunderstanding of their behavior throughout the entire loading history.The three- dimensional 20-node brick elements are used tomodel the concrete, while the reinforcing bars are modeled as axialmembers embedded within the concrete brick elements. Thecompressive behavior of concrete is simulated by an elastic-plasticwork-hardening model followed by a perfectly plastic response,which terminate at the onset of crushing. In tension, a fixed smearedcrack model has been used.
