This research was investigated on the increase in strength capacity among different five wood-to-wood connections. Group using small diameter bolts with equal area loss has the highest increase in strength capacity, secondly the group inserted plywood, thirdly the group used glued bolt, and lastly the group inserted rubber plate. These groups showed at least 10% increase in strength capacity more than existing connection groups. Therefore, these results can be applied to develop the new highly efficient connection. To select suitable connection configuration and materials, however, economical advantage and increase in strength capacity and the difficulty should be considered by the additional works.
