The paper presents an automated procedure, named META-FORMA (MEchanical-Typological Approach FOR Masonry Aggregates), to investigate the global seismic performance of masonry aggregates according to a simplified approach. The proposed procedure faces the challenge of using few mechanical and geometrical parameters of individual buildings belonging to an existing masonry aggregate as the input of a proper vulnerability algorithm based on the direct interaction between the programming software MATLAB and the structural analysis and design software POR2000. In this way, all possible combinations of the input parameters can be taken into account and a large set of numerical models is generated and analysed by nonlinear static analyses. The output of the procedure is represented by the bilinear capacity curves of the equivalent single degree of freedom models and by the values of the capacity/demand ratios. The entire approach has been firstly accurately defined and after applied on the pilot case study of the historical centre of the municipality of Foggia, Puglia, Southern Italy. The main advantage that META-FORMA offers is the possibility to generate a wide mechanical/typological-based database, which provides a direct and simplified estimate of the seismic behaviour of masonry aggregates by knowing only few parameters, being at the same time simple and time-saving. Albeit the presented procedure has only developed for building aggregates with linear configurations and composed by the same repeated structural units, META-FORMA is open to further development and modification for accounting any kind of aggregation form.

该论文提出了一个名为META-FORMA的自动化程序(Mechanical-Typological Approach FOR Masonry Aggregates)，根据简化方法研究砌体骨料的全球抗震性能。所提出的程序面临的挑战是，基于编程软件 MATLAB 与结构分析和设计软件 POR2000 之间的直接交互，使用属于现有砌体骨料的单个建筑物的少数机械和几何参数作为适当脆弱性算法的输入。通过这种方式，可以考虑输入参数的所有可能组合，并通过非线性静态分析生成和分析大量数值模型。该过程的输出由等效单自由度模型的双线性容量曲线和容量/需求比值表示。整个方法首先被准确定义，然后应用于意大利南部普利亚大区福贾市历史中心的试点案例研究。主要优点是META-FORMA提供了生成广泛的基于机械/类型学的数据库的可能性，该数据库通过只知道几个参数来提供对砌体集料的地震行为的直接和简化的估计，同时简单且省时。尽管所提出的程序仅开发用于构建具有线性配置并由相同重复结构单元组成的聚合，但META-FORMA对进一步开发和修改以计算任何类型的聚合形式持开放态度。
