The first purpose of this paper is to quantify the variation of physical deterioration of components of a building on the basis of the maintenance cost and to make the pattern of deterioration curves by the combinations of simple maintenance models. The second is to grasp the characters of deterioration of components by the three patterns of deterioration curves, which we make on the basis of the maintenance cost data of one building. The results are summarized as follows : (1) We quantified the variation of physical deterioration of components of a building on the basis of the maintenance cost. (2) We classified the maintenance type into three types, which are a regular maintenance, a small scale repair and a large scale repair. (Fig.4) And we made the three patterns of deterioration curves by seven combinations of simple maintenance models. Three patterns are a straight motion type, an accelerated motion type and a negative accelerated motion type. (Fig. 5) (3) On a system and a subsystem level, we made deterioration curves of many components on the basis of the maintenance cost data of one building. (Fig.6) And we made a graph of regression curves (y=a・t^m). (4) On a subsystem level, almost patterns of deterioration curves belonged to an accelerated motion type. On a system level except the external and internal finishing materials which didn't have a regular maintenance, almost patterns belonged to a straight motion type or an accelerated motion type which was akin to a straight motion type. The latter examples are those of the drainage and private generator system. Only the pattern of the inner ceiling belonged to a negative accelerated motion type. (Table 3〜5) (5) The mark (Fig.8) indicates the characters of deterioration and the maintenance type of each components. (Table 6. 7)
