单层空旷砖房系指没有承重横墙或具有抗震能力的横墙间距较大,内部空间比较高大,采用砖柱或砖壁柱承重的房屋,如影剧院、礼堂、食堂,厂房和仓库等。虽然这类房屋在整个城市建筑中的比例不大,但就其使用功能而言,却是人们经常密集活动的公共场所和国家财产集中的地方。一旦遭受地震,直接威胁着人民生命和国家财产的安全。因此,在城市震害预测和房屋抗震加固工作中,对这类房屋进行正确的抗震能力评定是十分重要的。 Single-storey empty brick houses refer to houses with no load-bearing cross walls or cross-walls with seismic resistance, large internal spaces, and brick or brick pilasters such as theaters, auditoriums, canteens, factories and warehouses. Although the proportion of such houses in the entire city building is small, in terms of its use functions, it is a public place where people often intensively move and where the national property is concentrated. Once it suffers an earthquake, it directly threatens the safety of people’s lives and national property. Therefore, it is very important to assess the correct earthquake resistance of these houses in the prediction of earthquake damage and the reinforcement of buildings.
