Abstract
The target of this study is a wood-concrete composite floor deck system with shear connector. Though this composite floor has spread in European area, in Japan the use has been limited for the part of timber-based apartments and schools. The floor deck may spread in the near future because Japanese building standard law was revised and high performance is required for fire- and sound-proof. In this paper, the results of bending test and long-term loading test is described as a feasibility study. The result of shear performance of shear connecter between timber beam and reinforced concrete slab is also described. They are summarized in 1) the composite deck increases 50% in strength to superposition of individual strength and more than 500% in stiffness to simple timber beam, 2) the deformation after 50years reaches 400% against initial deformation which is extremely larger than simple timber beam, 3) initial stiffness of the deck is estimated using equations proposed in the past study, but it is necessary to consider the effective width of concrete deck.
