ABSTRACT

In this study a seismic risk analysis of masonry buildings based on damage data of L’Aquila 2009 earthquake is presented. Typological loss curves and Expected Annualized Losses (EAL) values are presented, starting from the data collected into AeDES forms available in the Da.D.O. database. A completion is proposed for improving the sample statistical significance, and correctly including undamaged and not surveyed buildings that suffered low shaking values. Finally, the loss curves proposed permits to economically assess the effectiveness of some local and very frequent interventions (such as chains/ring beams), and their consequent impact in seismic risk mitigation.

摘要

在这项研究中，提出了基于拉奎拉 2009 年地震破坏数据的砌体建筑的地震风险分析。从收集到 Da.DO 数据库中可用的 AeDES 表格中的数据开始，呈现了类型损失曲线和预期年化损失 (EAL) 值。为提高样本统计显着性，并正确包括未受损和未调查的遭受低震动值的建筑物，提出了一种完成方法。最后，建议的损失曲线允许经济地评估一些局部和非常频繁的干预措施（如链/环梁）的有效性，以及它们对减轻地震风险的影响。
