Development of Japanese Enhanced Fujita Scale

Outline of Degree of Damage and Corresponding Wind Velocity Estimation for Timber Residences

Abstract

This paper illustrates outline of degree of damage and corresponding wind velocity estimation in the case of Timber Residences, which will be aimed to contribute to the development of Japanese version of Enhanced Fujita (EF) Scale. First, the authors organized eight degrees of damage (DODs) on the basis of past damage examples. Second, in order to estimate instantaneous wind velocity corresponding to DODs, load test data of timber roofing components and clay tiles and horizontal deformation performance of structural components were used respectively.
