DEVELOPMENT OF TIMBER MOMENT RESISTING JOINT WITH STEEL SIDED SCREWED JOINT PART 1 : A STUDY ON DETAIL AND DESIGN METHOD OF BEAM-END JOINT

Abstract

We developed a timber semi-rigid frame construction system composed with coupled glulam members jointed by screws with steel side plate and high-tensile bolts. We conducted cyclic loading test for the single screwed joint of glulam with steel side plates, tensile test for the full-thread screwed joint embedded in glulam using reinforcement to restrain splitting failure of glulam, the bending tests for the moment resisting joints to confirm the characteristics of the failure behaviors, the reinforcement efficacy by the full-thread screws and the estimability of their mechanical behaviors from single screwed joint properties.
