Fragility functions are fundamental for the assessment of seismic safety of structures or the loss assessment of a portfolio of assets. The present paper describes a procedure to derive fragility functions representative of Portuguese reinforced concrete precast buildings. This goal was achieved following an analytical methodology considering the result of hundreds of nonlinear static analyses, whose building models reflect both mechanical and geometrical characteristics of the Portuguese industrial building stock. Considering the specificities of this typology, and in particular the connections between the structural members, a recently developed macro-element was employed, which enables the explicit simulation of friction and dowel mechanisms. The fragility analyses considered both structural and non-structural limit states, and the findings indicate a poor seismic performance, even under low seismic demand.

易损性功能对于评估结构的地震安全性或资产组合的损失评估至关重要。本文描述了一种导出代表葡萄牙钢筋混凝土预制建筑物的脆性函数的程序。通过考虑数百种非线性静态分析结果的分析方法论实现了这一目标，其非线性分析的建筑模型反映了葡萄牙工业建筑群的机械和几何特征。考虑到这种类型的特殊性，特别是结构构件之间的连接，采用了最近开发的宏单元，它可以对摩擦和销的机理进行显式仿真。脆弱性分析同时考虑了结构性和非结构性极限状态，
