We developed a one-way slab system composed with cross laminated timber (CLT) and glulam coupled by lag-screws. Firstly, we conducted element test for the single lag-screwed joint of glulam and CLT to grasp the joint properties as composite beam and cyclic loading test for the lag-screwed joint of glulam-to-CLT panel and CLT panel seams for horizontal diaphragm. Secondly, we conducted the bending tests for CLT slab with glulam ribs to confirm the characteristics of the failure behaviors, the coupling efficacy by the lag-screwed joint and the estimability of their mechanical behaviors from single lag-screwed joint properties.
