Authors develop the two-way flat slab system that is layered CLTs so that the strong axial direction of CLT (Cross Laminated Timber) is orthogonal. GIR (Glued-in rod) joint system is used for joining between CLT. FEM analysis for two-way flat slab using CLT designs is made based on element experiments and the validity of the analysis is compared with keyed beam and several actual measurements of two-way flat slab using CLT in the building.
