This paper examines the influence of the end distances on the occurrence of stress concentrations in timber bolted joints. The effect of the anisotropic character of the wood on the stress distributions was also analyzed. The use of a theoretical model based on the method of the complex functions to calculate the stresses in a timber joint is presented. Minimum edge and end distances as identified in various design codes for timber bolted joints loaded parallel-to-grain are shown. Perpendicular-to-grain tensile stress concentrations for some softwoods and hardwoods are presented. Reducing the end distance does influence the magnitude of the tensile stress concentrations. It is established analytically that when adequate distances are used at the sides of the bolted timber joint its behavior is explicitly ductile.
