Abstract Traditional methods focus on the ultimate bending moment of glulam beams and the fracture failure of materials
with defects, which usually depends on empirical parameters. There is no systematic theoretical method to predict
the stiffness and shear distribution of glulam beams in elastic-plastic stage, and consequently, the failure of such
glulam beams cannot be predicted effectively. To address these issues, an analytical method considering material
nonlinearity was proposed for glulam beams, and the calculating equations of deflection and shear stress distribution for different failure modes were established. The proposed method was verified by experiments and
numerical models under the corresponding… More >
