This study presents a building classification scheme for residential houses in Malawi by focusing upon informal construction, which accounts for more than 90% of housing in the country with the highest urbanisation rate in the world. The proposed classification is compatible with the Prompt Assessment of Global Earthquakes for Response (PAGER) method and can be used for seismic vulnerability assessments of building stock in Malawi. To obtain realistic proportions of the building classes that are prevalent in Malawi, a building survey was conducted in Central and Southern Malawi between 10th and 20th July 2017. The results from the survey are used to modify the PAGER-based proportions of main housing typologies by reflecting actual housing construction in the surveyed areas. The results clearly highlight the importance of using realistic building stock data for seismic risk assessment in Malawi; relying on global building stock information can result in significant bias of earthquake impact assessment.

马拉维用于地震风险评估的房屋建筑分类方案

这项研究以非正规建筑为重点，提出了马拉维居民住宅的建筑分类方案，该方案占世界上城市化率最高的国家住房的90％以上。拟议的分类与“全球地震反应快速评估”（PAGER）方法兼容，并且可用于马拉维建筑材料的地震易损性评估。为了获得马拉维普遍存在的实际建筑等级比例，2017年7月10日至20日在马拉维中部和南部进行了建筑调查。调查的结果用于修改基于PAGER的主要住房类型的比例，方法是：反映调查区域的实际住房建设。结果清楚地表明了使用现实的建筑存量数据进行马拉维地震风险评估的重要性；依赖全球建筑存量信息可能导致地震影响评估的严重偏差。
