ABSTRACT

This work presents a comprehensive strategy for analysing the complex seismic response of five Italian historical URM buildings, corresponding to different periods until 1920s. One distinctive feature of historical buildings is the need for integrating global modelling and local response of structural portions, due to possible activation of local failure modes interacting with the overall dynamic building response. Global behaviour is analysed via pushover and dynamic analyses of 3D equivalent-frame models. An original approach is adopted for assessing local out-of-plane mechanisms, accounting for their dynamic response to input time histories, filtered by the global response of the 3D model.

摘要

这项工作提出了一种综合策略，用于分析五座意大利历史 URM 建筑的复杂地震响应，对应于 1920 年代之前的不同时期。历史建筑的一个显着特征是需要整合全局建模和结构部分的局部响应，因为局部失效模式可能会激活，并与整体动态建筑响应相互作用。通过 3D 等效框架模型的 Pushover 和动态分析来分析全局行为。采用一种原始方法来评估局部平面外机制，解释它们对输入时间历史的动态响应，并通过 3D 模型的全局响应进行过滤。
