| 内容記述 | In Japan, almost all of buildings were considered as “consumables”. However steel products will run short in these 40 years in the world. The giant industrial waste will break out when reinforced concrete buildings are pulled down. Considering such conditions the new concept of durability of existing buildings is proposed here. This paper is discussed about the life cycle cost and asset management of existing reinforced concrete buildings based on the seismic performance. Extending the life of existing buildings to more than one hundred years, the occurrence possibility of giant earthquake is discussed and the installation of the base isolation system to existing buildings is proposed. Through the case analytical study of dynamic response to the buildings due to giant earthquake inputs the damage grade was evaluated among three cases of buildings; non-strengthened building, seismic strengthened building and base isolation building. The cost evaluation for such seismic device and running cost was discussed. The ratio of the initial construction cost to running cost of building showed that the building with high construction cost is much smaller than total life cycle cost to the building with cheaper initial construction cost from the viewpoint of the concept of asset management. Such running cost is composed of reconditioning, administration, effective management and preservation.In Japan usually the initial cost (construction cost) occupies around thirty percent of total life cycle cost (initial cost + running cost) Through the analytical process, following recommendations were proposed. (1) The installation of base isolation system to existing building is much effective to the viewpoint of asset management of existing buildings. (2) The damage of existing building which was based on the old seismic design code due to earthquake caused additional disadvantageous situation such as repair works and business loss during the repair works. | |||||||
