Based on finite element analysis (FEA) in ABAQUS software, a numerical simulation was proposed to accurately describe the damage behavior and performance of the model. Nonlinear constitutive relationships and other characteristics of different materials, influencing factors such as the length of CFRP, the layer number of CFRP and the wood interface under finger joints were under consideration. The results show that the ultimate bearing capacity is increased by CFRP. The stress is mainly concentrated on the CFRP material.

Key words: component model, finger joint, timber beams, CFRP
