摘要提高传统建筑的抗震能力是保护文化遗产和提高其安全性的必要条件。这对里斯本的老砖石建筑（“Pombalino”、“Gaioleiro”和“Placa”）尤其重要，这些建筑仍用于住房和服务。考虑到这一点，本文重点对这三种类型的建筑进行抗震评估。基于等效框架模型方法对建筑物进行建模，确定其动力特性，并进行非线性静力（pushover）分析。此外，针对里斯本的抗震要求，对此类建筑类别的抗震性能进行了定义和比较。最后，为了支持地震风险和损失估计研究，进行了概率评估，并推导出每种建筑类型的易损性曲线。
AbstractImproving the seismic resistance of traditional buildings is essential for preserving cultural heritage and increasing their safety. This is especially important for old masonry buildings in Lisbon (“Pombalino”, “Gaioleiro” and “Placa”), which are still used for housing and services. Taking this into account, this paper is focused on the seismic assessment of these three types of buildings. The buildings were modelled based on the equivalent frame model approach, their dynamic characteristics were determined and non-linear static (pushover) analyses were performed. Furthermore, for the seismic demand of Lisbon, the seismic performance of such building classes was defined and compared. Finally, with the aim of supporting seismic risk and loss estimation studies, a probabilistic assessment was carried out and the fragility curves for each building type derived.
