In this paper, the stress-strain tests are performed on Gaboon (Aucoumea Klaineana Pierre) specie in room temperature and humidity. This specie is used, in major part, in collective, individual and industrial construction, in timber structure and also in the fabrication of paper and veneer wood products in Europe. 15 samples have been tested under monotonous loading and 6 others in 5 cycles compression loading with different levels. According to the typical load stress-strain curve, the elastic moduli are obtained and the comparison between envelope of the cyclic load curve and the monotonous loading curve is achieved. The evolution of continuous displacement versus number of cycles shows three different zones representing the mechanical behaviour of the specie. The obtained results are in accordance with these proposed in the literature and the European code and bring important informations to the Gaboon's timber building.
