FIELD SURVEY INTO DETERIORATION AND DEGRADATION STATES FOR STRUCTURAL MEMBER OF WOODENHOUSE

Abstract

High durability of wooden structure can be obtained by preventing it from termite damage and decay which would weaken the strength of the wood. In this study, we have performed field surveys of wooden houses in similar conditions with regard to their age, location, plan and structure in order to collect data of the actual termite damage and decay. Based on the quantum analysis of the data, we have clarified the relationship between locations of the damages and their deterioration progress.
