| Resumo: | The pile caps are of great importance for the balance of structure and among the main
difficulties for the dimensioning is the fact that there is no consonance when dealing
with the model of dimensioning and behavior of these elements, which leaves various
gaps on the considerations that should be made in the dimensioning, generating
discrepancies, for example, the values of the compression stress in the connecting rod
and the steel area value. This research led to an analytical study, compared to previous
experimental tests by Delalibera (2006) and Munhoz (2014), using national and
international standard codes, with the objective of evaluate the stress limits in nodal
regions. Faced with this, we observe the spanish standard code has bigger evaluation
forces and Santos (2013), ABNT NBR 6118 (2014) and CEB (1990) minors. Another
important factor was the discrepancy of the values of the resulting of traction of the
theoretical and experimental tie rods, where it presented variations according to the
pile cap, but in all cases there was conservatism of the analytical methods, which may
be related to the influence of the secondary reinforcement, confinement and the
contribution of the tensile strength of the concrete. |
