Outline of Final Research Achievements

In this research, the author try to apply timber (particularly Cross Laminated Timber,CLT) to the floor of middle or large-size buildings (particularly tall building) made by steel frame. By applying CLT to the floor of all non-residencial buildings in Japan , the domestic timber market will increase 10,000,000 m3.
The result of this research is as follows.(1)Realization of the unity of the floor,(2)Expression of the performance of the synthetic beam,(3)Realization of the two hours fireproof system.
By the above, steel frame structure with CLT floor shows that it is feasible for the fireproof and structurally.
