Strength and failure properties of bulky (i.e. with thick substrate) adhesive joints with adhesively-bonded columns (ABCs) Subjected to external loads were investigated experimentally and analytically. From the experimental results, it was found that the strengths of the bulky adhesive joints with ABCs increased considerably when they were subjected to external tensile loads or lateral bending loads. And the joint strengths increased with increasing depths of the blind holes. The failure process of the joints with ABCs was simulated by the technique of element birth and death developed in the finite element method (FEM). The conclusions obtained from FEM coincide with those obtained from the experiments.
