AN EXPERIMENTAL STUDY ON KEYED BEAM DESIGN METHOD FOR TWO-WAY FLAT SLAB COMPOSED OF CROSS LAMINATED TIMBER

Abstract

Authors have developed a two-way flat slab system that is composed of double layered Cross Laminated Timber (CLT) in order that strong axial directions of CLT can be orthogonally arranged in the slab. Glued-in-rod (GIR) joint system is adopted for joining between the CLTs. Performance of GIR joint systems in several parts of the slab is investigated by using element experiments in tensile, and performance of CLT keyed beam for the CLT flat slab is investigated by using actual slab experiments in bending.
