Mortise and tenon are commonly used to connect beams and columns, and reinforced with wooden dowel. The strength of the joint is affected by the type, size and position of the dowel and also the timber species. This paper reports on the performance of mortise and tenon using two different types of dowels, namely, wood and steel. Structural size mortise and tenon manufactured using kempas, fastened with 20.6 mm diameter dowels were loaded in shear and bending. Connections were tested until failure. The European Yield Models (EYM) concept was applied when analysing the results. The strength of mortise and tenon fastened with steel dowels was higher than those fastened with wood dowel in both shear and bending tests. Based on failure mode, steel dowel exhibited yield mode Im when loaded in shear and bending, while wood dowel failed in mode IIIs when loaded in shear and mode IV when loaded in bending.
