PROPOSAL OF HYBRID STRUCTURE USING CLT PANELS AND STEEL BEAMS AND VERIFICATION OF SEISMIC PERFORMANCE BY SINGLE FRAME TESTS

CLT walls-steel beams hybrid structural system with steel plates and large-diameter bolts for the joints was proposed to accelerate promotion of mid-rise timber buildings. A full-scale static loading test was conducted on a partial frame consists of a steel beam and a CLT wall derived from targeted four-story building designed using the proposed hybrid structural system. From experiment, high average shear stress of 1.5 N/mm2 in CLT panel and ductile deformation capacity until story drift angle of 3% were observed.
