本文提出了一项正在进行的实验计划，旨在量化典型葡萄牙“gaioleiro”建筑加固前后的脆弱性曲线，足以进行全球地震风险评估。测试是在 LNEC 3D 振动台上对具有砖石剪力墙和木结构地板的 4 层无筋砖石建筑的 1:3 缩小模型进行的。描述了实验测试并总结了加固方案及其选择的原因。迄今为止获得的初步结果表明，该模型复制了这些建筑物的典型倒塌模式。
This paper presents an ongoing experimental programme that aims at the quantification of vulnerability curves of typical Portuguese “gaioleiro” buildings, before and after reinforcement, adequate for global seismic risk assessment. The tests are performed in the LNEC 3D shaking table on 1:3 reduced scale models of 4 story unreinforced masonry buildings with masonry shear walls and wood-framed floors. The experimental tests are described and the reinforcement schemes, as well as the reasons behind their selection, are summarized. The preliminary results obtained so far show that the models replicate the typical collapse modes of these buildings.
