既存木造軸組構法住宅の経年劣化

抄録

The quake resistance of the existing timber frame house decreases by the aged deterioration of the building. The architectural engineer in charge of a seismic evaluation must grasp a deterioration state of the building. A purpose of this study is to obtain information about the deterioration of the existing timber frame house. At first I showed an example about deterioration of the wooden member of the existing timber frame house and the deterioration of the foundation structure. Then, I carried out the concrete strength investigation about the foundation structure of the store combination house. This building was built with a timber frame house in 1968. As a result of investigation, the concrete strength was very different depending on the investigation positions. This investigation was carried out as a study session for architectural engineers.
