Abstract:
To design of the pile caps are utilized the strut and tie model and bending theory. The Model Blévot and Frémy [1] is one of the models used to design of pile-caps. Another method for the design of is Model Beam that used bending theory. In the model of French researchers to cross section of the column is proportional to the cross section of strut near the column. To check the influence of the cross section of the column in the structural behavior of the pile caps, experimental tests of the two pile caps were realized, varying the dimensions of the column and the high of the pile caps. Comparative analysis of experimental results with the results found by the Model Blévot and Frémy [1] was realized. Observed that the increase of the cross section of the column conferred the pile caps increase capacity portent.
