Mechanical properties of metal plate connection(MPC) wood truss joint specimens with four different orientations(AA: parallel-grain/longitudinal-metal-plate,EA: perpendicular-grain/longitudinal-metal-plate,AE: parallel-grain /perpendicular-metal-plate and EE: perpendicular-grain /perpendicular-metal-plate) were evaluated.The results showed that for 38 mm×89 mm dimensional lumber: 1) AA connection specimens produced the best tension property;2) the ultimate tension load increased as the metal plate width or length increased,but increasing the width was more effective;3) the ultimate tension load and stiffness both decreased as the connection gap increased.
