The paper focuses on analyzing mechanical behavior of a lap scarf joint with inclined contact faces and wooden dowels which is a commonly used connection for repairing damaged beams in historical structures. Experimental and numerical analysis were performed to investigate mechanical parameters such as stiffness and strength of this type of prosthesis. This study concentrates on investigating joints behavior under combined loading, compression and bending, and tension and bending. It was desired to simulate the real loading conditions found in historical timber trusses such as combined compression and bending for rafters or tension and bending for tie beams. Experimental work has been designed for testing the jointed beams in small scale subjected to pure bending, combined compression and bending and combined tension and bending. Finally, a finite element model was constructed and validated using experimental output and further used for estimating the strength and stiffness. Moreover, authenticity and aesthetics of such prosthesis for historical timber structures was explored through testing two different types of lap scarf joints i.e. two-face and three-face joints.
