Abstract
At the time of earthquake, it is important to obtain information on the internal structure when we carry out a rescue operation. For example, position of free space and fragile part in the collapsed houses. However, it is difficult to know the internal structure from external information alone. Therefore, this study aims to establish of a method for estimating the internal structure of collapsed houses. This study suggests an evaluation method with the living space deformation using Space Deformation Index. Space Deformation Index is evaluation index to evaluate compression or/and deformation of the living space, based on the analysis of the digital rubble model.
