ABSTRACT

In this study, a resident questionnaire survey was conducted for three reinforced-concrete high-rise condominium buildings in Sapporo. All three were subjected to the 2018 Hokkaido Eastern Iburi Earthquake. Resident experiences of shaking and damage due to the earthquake, the seismic measures taken before and after the earthquake, and conditions during the long-term blackout were evaluated by the survey. Resident anxiety and their difficulty in taking actions due to the shaking were relatively small, because the ground motions input to the buildings were not very large. The long-term power outage due to the earthquake had a great impact on the occupants. Particularly, the inability to use elevators caused a great inconvenience to the residents of higher floors, making it difficult for them to leave their dwelling units. Each of the three buildings was equipped with an emergency power supply; however, differences in the operation methods of these supplies affected the convenience of the occupants during the power outage. The inconvenience and anxiety caused by the shaking and the power outage left a strong impression on the residents. This may have resulted in motivation to make further earthquake preparations, such as stockpiling of flashlights, lanterns, food, and water, after the complex disaster.

摘要

在这项研究中，对札幌的三座钢筋混凝土高层公寓楼进行了居民问卷调查。这三个人都遭受了 2018 年北海道东部伊布里地震。调查评估了居民因地震而遭受的震动和破坏，地震前后采取的抗震措施以及长期停电期间的情况。居民的焦虑和他们因震动而采取行动的难度相对较小，因为输入建筑物的地面运动不是很大。地震造成的长期停电对住户影响很大。尤其是无法使用电梯，给较高楼层的住户带来极大的不便，难以离开住所。三座建筑物中的每一座都配备了应急电源；但是，这些用品的操作方法不同，影响了停电期间居住者的便利性。震动和停电造成的不便和焦虑给居民留下了深刻的印象。这可能导致了在复杂的灾难发生后进行进一步地震准备的动力，例如储存手电筒、灯笼、食物和水。
