Seismic resilience is a new approach in earthquake engineering, which addresses technical, organizational, social, economic and environmental aspects. The main purpose of a resilience system is to reduce economic or operational casualties, so as to return the community or the damaged system to natural conditions in the shortest possible time. Schools and education centers are especially important when it comes to designing seismic-resistant buildings, as they require higher safety margins than other buildings. Due to the inadequacy and lack of precision in previous structural regulations, many Iranian schools require rehabilitation as well as increased resiliency. For this research, a high school located in Zanjan city in Iran, as a sample of 5120 Iranian steel frame school buildings, is investigated for seismic resilience evaluation. Various schemes are considered for the retrofitting process. The nonlinear analysis is conducted for each scheme, while the reliability analysis is performed using FORM and the sampling method, all of which are effective and reliable methods that can assign the appropriate and feasible strategy for the retrofitting process. The reliability analysis shows retrofitting with the X-braced system to be the optimal retrofitted scheme because it has the lowest losses and highest seismic resilience indices. To examine the accuracy of common methodologies for assessing the resilience index, two common procedures of resiliency evaluation are chosen, and their resiliency parameters are compared. The results indicate that extracting resiliency parameters by means of vulnerability curves is more reasonable and accurate than using resilience curves. The results of this study could help stakeholders better select the appropriate option for retrofitting operations by considering account resiliency parameters, structural deficiency, and disaster risk reduction mitigations.

抗震能力是地震工程中的一种新方法，涉及技术，组织，社会，经济和环境方面。复原力系统的主要目的是减少经济或运营上的人员伤亡，以便在尽可能短的时间内使社区或受损的系统恢复自然状态。在设计抗震建筑物时，学校和教育中心尤为重要，因为它们比其他建筑物要求更高的安全裕度。由于先前的结构法规不充分且缺乏精确性，许多伊朗学校都需要修复以及提高弹性。为了进行这项研究，调查了位于伊朗赞詹市的一所中学，作为5120座伊朗钢架学校建筑的样本，进行了抗震能力评估。改造过程考虑了各种方案。对每种方案进行非线性分析，而可靠性分析则使用形成以及抽样方法，所有这些方法都是有效，可靠的方法，可以为改造过程分配适当可行的策略。可靠性分析表明，使用X支撑系统进行改装是最佳的改装方案，因为它具有最低的损耗和最高的抗震指数。为了检查评估弹性指数的常用方法的准确性，选择了两种通用的弹性评估程序，并比较了它们的弹性参数。结果表明，通过脆弱性曲线提取弹性参数比使用弹性曲线更合理，更准确。这项研究的结果可以通过考虑帐户弹性参数，帮助涉众更好地选择适当的方案来进行改造操作，
