ANALYSIS OF ANALYTICAL METHODS OF RIGID TWO PILES CAPS AND THE LIMITS TENSIONS OF THE NODAL REGIONS
Piles caps; Dimensioning; Behavior; Nodal regions
The piles caps are of great importance for the balance of the structure
and among the main difficulties encountered for the design 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 compressive
tensions in the connecting rod and reinforcement area. This research led to an analytical
study, compared to previous experimental tests by Delalibera (2006) and Munhoz
(2014), using national and international design methods, with the objective of evaluate
the limits and results that promote. Faced with this, we observe the spanish code as the
least conservative and Santos (2013), ABNT NBR 6118 (2014) and CEB (1990) as the
most conservative. 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.
