The area of this study will cover the location-wise seismic response variation of an electrical cabinet in nuclear power point (NPP) based on classical reliability analysis. The location-based seismic ground motion (GM) selection is carried out with the help of probabilistic seismic hazard analysis using PSHRisk-tool, where the variation of reliability analysis can be understood from the relation between the reliability index and intensity measure. Two different approaches such as the first-order second moment method (FOSM) and Monte Carlo Simulation (MCS) are helped to evaluate and compare the reliability assessment of the cabinet. The cabinet is modeled with material uncertainty utilizing Steel01 as the material model and the fiber section modeling approach is considered to characterize the section's nonlinear reaction behavior. To verify the modal frequency, this study compares the FEM result with recorded data using Least-Squares Complex Exponential (LSCE) method from the impact hammer test. In spite of a few investigations, the main novelty of this study is to introduce the reader to check and compare the seismic reliability assessment variation in different seismic locations and for different earthquake levels. Alongside, the betterment can be found by comparing the result between two considered reliability estimation methods.

本研究的领域将涵盖基于经典可靠性分析的核电站 (NPP) 电气柜的位置地震响应变化。基于位置的地震动（GM）选择是在使用PSHRisk工具的概率地震危险性分析的帮助下进行的，其中可靠性分析的变化可以从可靠性指标和强度测量之间的关系来理解。一阶二阶矩法（FOSM）和蒙特卡罗模拟（MCS）两种不同的方法有助于评估和比较机柜的可靠性评估。使用 Steel01 作为材料模型，使用材料不确定性对机柜进行建模，并考虑使用纤维截面建模方法来表征截面的非线性反应行为。为了验证模态频率，本研究将 FEM 结果与使用最小二乘复指数 (LSCE) 方法从冲击锤测试中记录的数据进行比较。尽管进行了一些调查，但本研究的主要新颖之处在于向读者介绍了检查和比较不同地震位置和不同地震级别的地震可靠性评估变化。此外，可以通过比较两种考虑的可靠性估计方法之间的结果来发现改进之处。本研究的主要新颖之处在于介绍读者检查和比较不同地震位置和不同地震级别的地震可靠性评估变化。此外，可以通过比较两种考虑的可靠性估计方法之间的结果来发现改进之处。本研究的主要新颖之处在于介绍读者检查和比较不同地震位置和不同地震级别的地震可靠性评估变化。此外，可以通过比较两种考虑的可靠性估计方法之间的结果来发现改进之处。
