Abstract

In present work, novel steel fiber reinforced concrete (SFRC) behavior nonlinearities were proposed depending on various experimental studies outcomes. Nine-noded Lagrangian finite elements procedure was developed using the proposed material behavior nonlinear relationships to investigate the performance of SFRC corbel. The stiffness matrix was determined in many ways dependent on the initial and tangential stiffness values. The results were given in terms of maximum deflections and crack formation of the corbel. Good agreement was observed between present numerical analysis results and that for other related studies. The average ratio between current numerical outcomes and other experimental results is about 0.89655 in terms of maximum displacements and ultimate loads.
