MAXIMUM RESPONSE EVALUATION OF TRADITIONAL WOODEN BUILDINGS BASED ON AMPLITUDE DEPENDENCY OF NATURAL FREQUENCY

Abstract

The objective of this study is to establish a method of evaluating the maximum response of traditional wooden buildings during strong ground motions by microtremor measurements which is used to evaluate their natural frequency. To clarify the relationship between the maximum response and the vibration characteristics, the shaking table test of wooden frame structure is conducted. Using response spectra method, the maximum response considering the damage by former earthquakes is evaluated from the expression of the amplitude dependency of the vibration characteristics. We confirm this method can evaluate the maximum response approximately.
