RESUMO

This paper presents the study about the bond phenomenon in High Performance Concrete, through the analisys of the flexibility of reinforced concrete beams with HPC. The bond was analyzed under the anchorage and cracking aspects, on longitudinal bars part spliced by transfix. Three types of beam models were analyzed, according to the manner which they were transfixed. For each model, the parameters adopted were: concrete strength, bar diameter, development lengths, cover of the bars and the behavior of the various splices. The results were also analyzed with the international equations for the bond prediction and NBR 6118:2003
