    This paper is based on a literature titled the “Outline of Various Demolition Methods and Their Evaluation” by the author which was presented to the Second International RILEM Symposium on Demolition and Reuse of Concrete and Masonry, 7-11 December, 1988, in Tokyo. The contents of this paper are the general application of demolition methods. Firstly, they are classified into eleven categories based on the breaking mechanism, and according to demand some of them are stated in 2-7 items. Secondly, the evalution of main demolition methods is mentioned and two large tables on evalurion are presented.

    Japan Society of Civil Engineers has revised standard specification for concrete structures in 1986, and limit state design method has been employed. Following the revision of JSCE code, some codes to design structures for specific use, such as highway bridges, are being examined for the revision into limit state design method. Though engineers are eager for getting information about the value of design loads and safety factors that would be employed in these codes, it is very hard to do so at this stage. Here, the design concept of JSCE code is introduced. Problems in adopting JSCE code to the codes for designing structures for specific use, and possible way to get solution of the problems are explained.

    The old school house in Kyoto was built on Meiji Era, 2 storied brick building for electrical engineering of Kyoto University. It is planned to reconstruct and preserve the old building at the same site. The new building is 5 storied SRC structure which contained a part of brick wall and entrance hall. This report deals with a reconstruction method and technical comment for deconstruction, cutting, moving, repairment and refreshment.

    Yokohama city Water Works practiced a reinforcing construction for “Tsurugamine water supplying bridge”, it was constructed 40 years ago, with the aim to improve the dynamic motion. For an examination for the dynamic motion of the bridge, the static and dynamic analysis was applied, and from the result of that a reinforcing for the foundation of bridge was required. The reinforcing is placing the cast-in-situ piles close to the old footings and building the new footings with the prestressed concrete technique, to connect the old footing with the new one. This report describes the survey, the design and the construction of the reinforcing for the foundation of the bridge.
