In order to develop a rational joint system in traditionally joined timber frame structures, we designed a new drift-pin joint composed of a steel pipe drift-pin with a glass-fibre-reinforced nylon (GFRP) plate inserted into a slit of the timber. Lateral resistance tests of the joint with a single drift-pin were conducted to evaluate the effects of drift-pin shape on maximum and yield loads. These properties were compared with a common drift-pin joint with a steel plate. The joint with a nylon plate had 60% of the stiffness, 90% of the maximum load and 90% of the yield load as compared to a steel plate. Both nylon and steel plate joints with steel pipe drift-pins had 80% of the lateral strength of common drift-pins. Maximum and yield loads of nylon plate joints with steel pipe drift-pins under reversed cyclic loads were equivalent to those under monotonic loads, and no failure of nylon plate had occurred under reversed cyclic loads at the yield resistance level after 150 cycles.
