Influência das dimensões da seção transversal do pilar e da excentricidade da força de compressão no comportamento estrutural de blocos sobre duas estacas

Resumo To design of the pile caps are utilized the strut and tie model and bending theory. The Model Blevot and Fremy [1] is one of the models used to design of pile-caps. Another method for the design of caps 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 column cross section in the structural behaviour 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 Blevot and Fremy [1] was realized. It was observed that the increase of the column cross section conferred the pile caps greater strength capacity.

Numerical analysis of two pile caps with sockets embedded, subject the eccentric compression load

The structural behavior of pile caps with sockets embedded is influenced by interface of column-socket, which can be smooth or rough. With intent to analyze the behavior of two pile caps with embedded socket, considering the friction between the column and the socket, with eccentric normal load, the numerical simulations were carried out, using a program based on the Finite Element Methods (FEM). In the numerical analysis the non-linear behavior of materials was considered, also the friction between the column and the socket. It was considered perfect bond between the reinforcement and the concrete around. It was observed that the embedded length is preponderant factor in the structural behavior of the analyzed element.
