Abstract :The wall area index and modulus of eccentricity of 30 wooden houses recently constructed in Totsuka Ward, Yokohama, using the skeleton system were investigated according to laws such as the Building Standard Law. The wall area index complied with the legal limits in all dwellings. However, although the dwellings were also within the legal maximum of 0.3, some had eccentricities above the recommended value of 0.15. Dwellings were analyzed by the quarter area method, and approximately one-third were found to be in violation of the 0.5 standard ratio for the wall area index. This can be considered one of the limits of the quarter area method, which is a simplified method. If we define the vertical correspondence rate as the fraction of supporting walls lying beneath a given wall on an upper story, this value would be low for many buildings.
