In this work, partial factors for the design of temporary scaffold structures are calibrated based on reliability calculations. Scaffolds are commonly designed in accordance with the rules in standards (e.g. EN12811, EN12810) and information found in codes of good practice. However, there is no clear proof that these design procedures result in an appropriate and consistent safety level for scaffold structures. The present study proposes appropriate target reliability levels for façade scaffolds, based on which partial factors are determined. The results are based on simulations of different scaffold design situations, considering samples generated by Latin Hypercube Sampling (LHS). The results of these simulations are processed by applying FORM analyses for buckling and yielding of the scaffold elements. As such, the inherent reliability corresponding to current design practice is determined. Based on the inherent and target reliabilities, partial factors are calibrated using two methods: the Adjusted Partial Factor Method and an optimisation procedure based on least-square averaging. Concluding, annual reliability indexes in the range 2.5–3.5 are found. These lead to partial factors lower than or equal to those used in current design practice. Hence, there is an optimisation possible in the design of temporary structures compared to current practice, leading to more economical scaffold designs.

在这项工作中，基于可靠性计算对用于临时脚手架结构设计的局部因素进行了校准。脚手架通常根据标准规则（例如EN12811，EN12810）和良好操作规范中的信息进行设计。但是，没有明确的证据表明这些设计程序会为脚手架结构带来适当且一致的安全等级。本研究为立面脚手架提出了适当的目标可靠性水平，基于此确定了部分因素。结果基于对不同脚手架设计情况的仿真，并考虑了拉丁超立方体采样（LHS）生成的样本。这些模拟的结果通过应用FORM分析来分析脚手架元件的屈曲和屈服。因此，确定与当前设计实践相对应的固有可靠性。基于固有可靠性和目标可靠性，可以使用两种方法来校准部分因子：调整部分因子方法和基于最小二乘平均的优化过程。最后，发现年度可靠性指标在2.5-3.5之间。这些导致部分因素低于或等于当前设计实践中使用的那些因素。因此，与目前的实践相比，临时结构的设计有可能进行优化，从而使脚手架设计更加经济。发现年度可靠性指标在2.5-3.5之间。这些导致部分因素低于或等于当前设计实践中使用的那些因素。因此，与目前的实践相比，临时结构的设计有可能进行优化，从而使脚手架设计更加经济。发现年度可靠性指标在2.5-3.5之间。这些导致部分因素低于或等于当前设计实践中使用的那些因素。因此，与目前的实践相比，临时结构的设计有可能进行优化，从而使脚手架设计更加经济。
