Abstract Iran is one of the most earthquake-prone areas in the world and the resulting losses and casualties have had long-lasting effects on both its economy and citizens. As a vital structure in any community, schools are expected to maintain their initial functionality during a seismic event to guarantee the safety of students and act as an emergency center immediately following an earthquake. The Ezgeleh-Sarpole-Zahab earthquake in 2017 was one of the most destructive earthquakes in Iran. The present research reviewed the performance of 17 Iranian school buildings during the Ezgeleh earthquake and outlines the damage to structural and nonstructural components. Overall, masonry schools exhibited satisfactory performance during the Ezgeleh earthquake, but one-story schools built between 1975 and 1985 experienced noticeable damage and required expensive reconstruction. The damage was limited to nonstructural renovations for school buildings which adhered to national seismic regulations and building codes. The results of this research highlighted the need to determine the vulnerability of educational centers and formulate plans for their rehabilitation in order to minimize the level of risk to communities and prevent the damaging consequences of natural hazards. In part II, the recovery process and resiliency calculation of the school buildings will be discussed.

2017 年 11 月 M 7.3 Ezgeleh-Sarpole-Zahab 地震后学校的恢复和重建;第一部分:地震后的结构性和非结构性损坏

摘要 伊朗是世界上最易发生地震的地区之一,由此造成的损失和人员伤亡对其经济和公民都产生了长期的影响。作为任何社区的重要结构,学校应在地震事件期间保持其初始功能,以保证学生的安全并在地震发生后立即充当应急中心。2017 年的 Ezgeleh-Sarpole-Zahab 地震是伊朗最具破坏性的地震之一。本研究回顾了 17 座伊朗学校建筑在 Ezgeleh 地震期间的性能,并概述了结构和非结构部件的损坏情况。总体而言,砌体学校在埃兹格莱地震期间表现令人满意,但 1975 年至 1985 年间建造的单层学校遭受了明显的破坏,需要昂贵的重建费用。损坏仅限于遵守国家地震法规和建筑规范的学校建筑的非结构性翻新。这项研究的结果强调需要确定教育中心的脆弱性并制定其修复计划,以最大限度地减少对社区的风险水平并防止自然灾害的破坏性后果。在第二部分,将讨论校舍的恢复过程和抗灾力计算。这项研究的结果强调需要确定教育中心的脆弱性并制定其修复计划,以最大限度地减少对社区的风险水平并防止自然灾害的破坏性后果。在第二部分,将讨论校舍的恢复过程和抗灾力计算。这项研究的结果强调需要确定教育中心的脆弱性并制定其修复计划,以最大限度地减少对社区的风险水平并防止自然灾害的破坏性后果。在第二部分,将讨论校舍的恢复过程和抗灾力计算。
