ABSTRACT

This paper deal with the mechanical behavior of some tropical glued species. Three tropical species have been correctly selected from four criteria (threat of extinction, availability, resistance and job class). The goal is to manufacture glued solid timber beams from hardwood (Staudtia kamerunesis And Ppterocarpus soyauxii) and softwood (Dacryodes Buettneri), the adhesive used is at the phenol. The Modulus of Rupture (MoR) and the Modulus of Elasticity (MoE) of four configurations are calculated and compare to the characteristics of soft wood. The results show the increasing in the strength and the stiffness of the beams made of Staudtia kamerunesis and Dacryodes Buettneri relative to the characteristics of the soft wood. While the characteristics of beams made up of Ppterocarpus soyauxii and Dacryodes Buettneri Slightly below the characteristics of the soft wood.
