The authors conducted horizontal loading experiments on a two-layer fishbone-shaped model consisting of timber assembly columns, CLT floors and glued in rod joints as a basic research on the development of a wooden flat slab structures for medium-scale buildings. Horizontal loading experiments show the kinematical properties of wooden flat slab structures. Further, semi-rigid joint frame model considering bending stiffness and shearing rigidity was constructed and the applicability of semi-rigid joint frame model was verified by conducted load incremental analysis.
