SANTOS, C.L.; JESUS, A.M.P. de; MORAIS, J.J.L.  e  LOUSADA, J.L.P.C.. Bearing properties of portuguese pine wood beneath a laterally loaded dowel. C.Tecn. Mat. [online]. 2008, vol.20, n.1-2, pp.45-51. ISSN 0870-8312.

The pine wood (Pinus pinaster Ait.) is one of the species with larger implantation in Portugal. Its use for structural applications requires an adequate knowledge of its mechanical behaviour. In particular, for designing doweled joints, it is essential to know the bearing properties beneath the dowel. This paper reports a comprehensive experimental program aiming the determination of the bearing properties of the Portuguese pine wood. The embedding strength is evaluated in longitudinal and radial directions according two alternative standards, namely the ASTM D 5764 and EN 383 standards. Results are compared with empirical relations proposed in design codes of practice (e.g. EC5). Also, foundation moduli are evaluated in both directions according both standards. The experimental work also includes the test of a single dowel double shear wood connection. Additionally, some elastic strength properties are evaluated from small specimens of clear wood in order to better characterize the mechanical behaviour of the wood species.
