Research on restoration, strengthening, and protection of cultural heritage buildings damaged in L'Aquila earthquake

为了制定评估和减轻遗产建筑地震风险的明确指导方针，对2009年意大利中部拉奎拉地震中受损的遗产建筑进行了调查。在调查的基础上，系统地分类了损坏情况和必要的应急措施。自1970年代以来，使用钢筋混凝土加固文物建筑的效果无法核实。这一发现表明，不仅要在加固前和加固过程中对文物建筑进行结构健康监测，而且要在加固完成后对加固效果进行验证。此外，基于对意大利国内外类似遗产建筑的调查，开发了基于知识的综合方法来修复、加强和保护遗产建筑免受地震风险。

To develop a definitive guideline for the evaluation and mitigation of seismic risk to heritage buildings, heritage buildings damaged in the 2009 L'Aquila earthquake in central Italy were investigated.Based on the investigation, the damage situation and necessary emergency measures were systematically categorized. The effect of strengthening work on heritage buildings by using reinforced concrete, undertaken since the 1970s, could not be verified. This finding shows that the structural health monitoring of heritage buildings should be performed not only to ensure structural stability before and during the strengthening work, but also to verify the strengthening effect after completion.In addition, based on investigations of similar heritage buildings inside and outside of Italy, integrated knowledge-based approaches were developed for the restoration, strengthening, and protection of heritage buildings from seismic risk.
