In order to promote application of domestic truss plate used for light frame wood construction,the authors selected three types of domestic truss plates and an imported truss plate as control to evaluate their ultimate bearing capacity, critical slip stiffness, failure forms, ductility and stress-strain changes in tensile process. The results showed that the ductility of the three domestic truss plates was all superior to the control and that the domestic truss plates with indentation showed the best single-tooth bearing capacity. Indentation or extension fringe tooth could improve connection performance of truss plates.
