Schools represent a reference point for communities in any part of the world. Therefore, their safety and resilience against natural catastrophes is of paramount importance. The recent 2015 Gorkha earthquake has unfortunately shown that Nepalese school buildings are highly vulnerable to seismic actions. Most of them are indeed constituted by low-quality unreinforced masonry (URM). The quantification of URM vulnerability is fundamental to estimate the risk associated to school building portfolios at territorial scale. This work discusses statistics available for Nepalese schools and then presents analytical fragility curves for three recurrent URM typologies covering more than 50% of the school building stock. The methodology adopted to derive fragilities is spectral-based and accounts for out-of-plane and in-plane damage potential in a single easy-to-use analytical framework. Inter-building, intra-building and record-to-record variabilities are directly considered in the analysis. The obtained fragilities integrate the studies available for the region and can be used for pre-/post-earthquake risk assessment and prioritization of interventions at country level.

学校是世界任何地方社区的参考点。因此，它们的安全性和抵抗自然灾害的能力至关重要。不幸的是，最近的2015年Gorkha地震表明，尼泊尔的学校建筑物极易遭受地震袭击。它们中的大多数确实是由低质量的非增强石工（URM）构成的。URM漏洞的量化对于估算与领土范围内的学校建筑组合相关的风险至关重要。这项工作讨论了可用于尼泊尔学校的统计数据，然后提供了覆盖50％以上学校建筑存量的三种URM经常性分析类型的易碎性曲线。推导脆弱性所采用的方法是基于光谱的，并且在单个易于使用的分析框架中考虑了平面外和平面内的损坏可能性。在分析中直接考虑建筑物间，建筑物内和记录间的差异。获得的脆弱性综合了该地区的现有研究结果，可用于地震前/震后风险评估以及国家一级干预措施的优先级划分。
