The present study deals with cracking analysis of concrete beams under monotonic loadings by means of a quasi-static evaluation. The theoretical basis herein used is lies on the Fixed Smeared Crack Approach taking into account Fracture Mechanics within a Finite Element algorithm for the numerical solution of the problem. The main objective is to propose a computational model for the calculus of instantaneous deflection and the simulation of cracking in concrete beams under service loadings. On this purpose, diverse beams evaluated by may authors where analyzed. The results of this study cases are presented through and force-displacement curves, cracking propagation and the evaluation of the ultimate resistance of the beam. Within the computational algorithm, a fragile crack stress-strain relation was implemented. On this way, for the analyzed elements it was demonstrated that the model herein used can predict adequately cracking processes and instantaneous deflections of concrete beams considering existing experimental results.
