RESUMO

There is a lack of knowledge about pile caps. Studies concerning these elements are limited to the case of pile-caps subjected to centered forces without connection elements. In this context this research aims to clarify some doubts about the behavior of pile caps under centered forces and bending moment. The behavior of four pile-caps with partially embedded socket subjected to moment in two directions was studied. A nonlinear numerical study was conducted to analyze two pile-caps models designed as part of industrial and commercial buildings. To verify the representativeness of the numerical model adopted, comparative analyze were performed using numerical and experimental data found in previous researches. The reinforcement and connection type were the variable parameters in the analysis of the two pile-caps. The results have shown that in the case of rough connection there occurs the formation of struts from the top of the socket wall. In the case of smooth connection, the transfer of forces from the column to pile-cap occurs through friction forces in the socket/column connection.
