Abstract

Existing wooden buildings are vulnerable to earthquake damage. In Japan, where earthquakes occur frequently, it is important to know the condition of wooden buildings. Therefore, tools for evaluating seismic capacity are essential. However, as wooden buildings are built in various ways no perfect tool is available. Especially, the conventional tool is inadequate to evaluate the aging deterioration and the changes that occur before and after earthquakes. In addition, it is costly and time-consuming. The evaluation that can find the aging deterioration of wooden buildings easily and economically is thus needed. In this paper, we focus on a complexity index from inspiration that there is a similarity between human and wooden buildings. The aim is to evaluate the aging deterioration of wooden buildings in a simple manner. The paper discusses the possibility of using Approximate Entropy as a performance index of seismic capacity for wooden buildings.
