Etude de la fatigue d'origine hygroscopique d'un assemblage lamellé-collé en essences mélangées

Abstract : The evolution of the strain-state of douglas fir-poplar glulam specimens is evaluated by analysis of the recorded pictures of a strained surface. The strain values are calculated from displacements of selected points, from digitalized images of the most strained surfaces of specimens aged during relative moisture cyclic conditions varying between 5% and 95%. No significant variations of maximum strain levels are revealed along the twelve 14-days drying-swelling cycles. These results are consistent with the gluebond integrity and stability of surrounding cracks, initialized during the first cycle
