RESUMO
This work presents a theoretical and experimental study of timber piles, including the instrumentation of the timber piles of a wooden bridge foundation, in order to generate recommendations for the project of this type of foundations for small wooden bridges. The experimental work was made in two stages. In the first stage the mechanical properties of timber pile had been determined using bending and compression tests of structural size specimens and of small clear wood specimens. In the second stage the properties of the ground had been determined, by means of subsoil exploration, and of the timber piles by means parallel compression tests in small clear wood specimens. In this stage, first time in Brazil, an analysis of the behavior of timber piles in the ground was made, by means of Pile Diver Analyser (PDA). The results show that timber piles are excellent structural elements for use in foundations
