JAUE2018-072 Operation Policy for Water-Supply Facilities of High-Rise Condominium Buildings at the Time of Earthquake Disasters

Abstract

As six years have passed since the Great East Japan Earthquake, there is a growing need to protect both living places and workplaces and to maintain the functions of cities and buildings on the premise of preserving life at the times of disasters. Apartment houses are more robust and safer than detached houses because the buildings are made of reinforced concrete and steel-reinforced concrete. A public evacuation center is a facility where victims who were forced to leave their homes owing to complete or partial destruction are received in appropriate rooms. Therefore, when a major earthquake occurs, residents of multifamily dwellers are allowed to return to their homes at home I have to make assumptions to live. However, in the case of a major earthquake, services such as water supply and drainage and electricity stop working in most cases, so it is difficult to continue living at home after such earthquake. Therefore, it is necessary to consider how to maintain the minimum life standards in the building on the premise that it will be damaged by the lifeline and the facilities of the building. In order to keep the minimum life standards in the building until its restoration, it is important to systematically utilize a limited amount of water and electricity inside the building. Therefore, in this research, we consider the operation policy of water-supply facilities to maintain the minimum life standards in a building during the period from disaster to recovery for the case of two high-rise apartment houses with different water-supply methods It is aimed to do.
