社会基盤の維持・補修システム構築のための解析的アプローチ

The number of accidents of infrastructures due to aging has been recently increasing and the aging of it has become a serious problem. Aggressive environment and in-service loading can cause the resistance deterioration of the infrastructures such as tunnel and highway bridge. It is necessary to formulate time-dependent reliability analysis on account of developing the rational maintenance strategy and reliable prediction of service life of infrastructures. In this report, the reliability function of deteriorating infrastructures due to aging under load combinations consisting of dead, live and main external load of earthquake is analytically derived, applying the advanced first order and second moment method with the statistics of the residual resistance of each failure mode of element which has survived up to time

民家移築の研究

Although there is the report of removing and reconstruction much conventionally, the perspective is not clear in the folk house.The purpose of this study analyzes the removing and reconstruction of the folk house in Japan and shows the diverse aspects of removing and reconstruction, and it is to clarify the meaning of removing and reconstruction.This dissertation consists of an introduction, main subject 6 chapters, a chapter with, a conclusion.In an introduction, I spoke the purpose of the study and a method, a study of the past and problems, the constitution of the article, the definition of the term.With Chapter 1, I considered amount and local difference of removing and reconstruction of a folk house in Tokyo and Kanagawa prefecture. It became clear to be distributed 284 removed and reconstructed folk houses among 2259 investigated folk houses in this area and at least, thatʼs at the rate of 13%.With Chapter 2, I took result of Chapter 1 and considered the substance of the removing and reconstruction private house in Tokyo and Kanagawa prefecture.There is no difference between Tokyo and Kanagawa pref., in the "age" distribution about removing and reconstruction of the folk house. 19 century latter terms, the "reason" of "fire disaster" is most. The "distance" is many from neighboring area, but 20 century first half decreased removing and reconstruction distance. Removing and reconstruction was done in order to obtain the residence quickly and cheaply. As the prerequisite, it is thought that the similar type residence was distributed widely inside area.With Chapter 3, I considered the amount of private house removing and reconstruction in the whole country and the local difference.It became clear to be distributed 161 removed and reconstructed folk houses among 2,395 investigated folk houses in all over Japan and at least, that s at the rate of 7%. It was Toyama, Ishikawa, Miyazaki and Kagoshima prefecture that showed a high ratio. Above all, the ratio amounted to 30% in Toyama. The Bunttoho type in Miyazaki and Kagoshima, it was seen that one side was supplemented by that. A few ratios was Hokkaido, Aomori, Iwate, Miyagi, Fukushima, Ibaraki, Tochigi, Chiba, Nagano, Mie, Nara, Ohsaka, Ehime and Saga prefecture, elucidation of a reason is a future problem.With Chapter 4, I considered folk house removing and reconstruction in Japan and got the following conclusion.Movement distance of folk house at removing and reconstruction is 8.6km in the whole country.It is 5.3km when it excludes marine transportation. The average of years from a building of folk houses to removing and reconstruction is 79.The mutual relations of "Times", "reason", "distance", "period" in folk house removing and reconstruction, are as follows. As for " reason", a change by "times" is big, as for "distance" is accepted by some "reason". As a result, some relations were seen in "times" and "distance". However, the strong correlation was not accepted between other factors for "period".With Chapter 5, I considered the folk house removing and reconstruction of the country appointment important cultural property.I showed that the removing and reconstruction of the important cultural property folk house were common not a special example in Japan and both prefectures.With Chapter 6, I considered the save removing and reconstruction of the country appointment important cultural property folk house.I showed that the save removing and reconstruction of the important cultural property were different from the general folk house removing and reconstruction.I summarized the consideration contents of each main subject chapter by the conclusion and raised it generally
