ULTIMATE HORIZONTAL RESISTANT FORCE DISTRIBUTION OF JAPANESE WOODEN HOUSES AND THEIR ESTIMATION METHOD(Structures)

Abstract

In this paper, the ultimate horizontal resistant force of Japanese wooden houses considering the stiffness of both floor and non-structural walls is discussed. The analytical model has the restoring force characteristic composed of the floor, bracing bearing walls and non-structural plaster board walls. The results may be summarized as follows : The increase of floor stiffness does not make the ultimate horizontal resistant force increased efficiently. The easy calculation method gives the lower limit of the ultimate horizontal resistant force.
