Script associated with the publication "The role of load variations in assessing credible dike failure probabilities: balancing load and strength uncertainties"

This dataset contains the script used for the conceptual analysis in the research paper <em>“The role of load variations in assessing credible dike failure probabilities: balancing load and strength uncertainties.”</em><br>The study investigates how load variations influence reliability updating and the assessment of credible failure probabilities. The script implements the construction of fragility curves and the direct reliability updating procedure described in the manuscript. It allows users to define and vary load variations and fragility curves (or strength uncertainties), and then apply reliability updating using Bayesian analysis on the fragility curve, where the evidence is survival at an observed load level.<br>The outputs include key figures illustrating the methodology, and the main results and data of the conceptual analysis.

本数据集包含研究论文《载荷变异在可信堤坝失效概率评估中的作用：平衡载荷与强度不确定性》中用于概念性分析的脚本。本研究探讨载荷变异对可靠性更新及可信失效概率评估工作的影响机制。本脚本实现了该手稿中所述的易损性曲线（fragility curves）构建与直接可靠性更新流程，支持用户自定义并调整载荷变异参数与易损性曲线（或强度不确定性），随后可基于贝叶斯分析（Bayesian analysis）对易损性曲线执行可靠性更新，其中观测载荷水平下的结构存活状态作为分析证据。输出内容涵盖用于阐释研究方法的关键图表，以及本概念性分析的核心结果与配套数据。
