Special Issue Information

Dear Colleagues,

The evaluation at a large scale of seismic risk maps is a challenging and crucial task to correctly predict potential future losses, to plan emergency management procedures, and to define effective mitigation policies.

Seismic input should be defined through a probabilistic seismic hazard analysis, or a scenario-based assessment may be performed at regional or urban scale. The inventory of the built environment is another crucial issue, which requires the classification into homogeneous sets on the base of the available taxonomy (structural material, building age, number of stories, etc.) and characterized by a combination of specific regional structural features which are relevant for the vulnerability.

The fundamental step of seismic risk analysis is the assessment of the building’s vulnerability, in terms of fragility curves that may be derived through different approaches (empirical, mechanical, hybrid, etc.). Scientific papers are expected both on residential and strategic or special buildings.

The evaluation of consequences (casualties, unusable buildings, etc.) and economic losses (direct and indirect) is another topic of this Special Issue.

This Special Issue will collect the main results of MARS (Seismic Risk and Damage Maps in Italy), a big national project funded by the Civil Protection Agency, within the activities of the ReLUIS consortium (Network of the University Laboratories of Seismic Engineering). The aim is to compare the developed procedures with other experiences worldwide; hence, other contributions are welcome.

We look forward to your contributions.

Seismic events that have occurred in Italy in recent decades have shown the significant vulnerability of the Italian building stock. In particular, residential masonry buildings have suffered serious damage, highlighting the need to plan effective mitigation strategies as soon as possible. In this context, this study aims to evaluate the effectiveness of possible retrofit interventions for masonry buildings. Fragility curves of macro-classes of residential masonry buildings have been developed in both as-built and retrofitted conditions within the DPC-ReLUIS agreement (Department of Civil Protection—Network of University Laboratories for Earthquake Engineering). In particular, three sets of fragility curves, developed by the University of Padova (UniPD) and the University of Genova (UniGEa and UniGEb) are discussed and compared herein. The three models show similar estimates of the expected structural improvements for the examined retrofit interventions when applied to the building macro-classes, although some differences, due to the different analysis approaches, can be observed.

Within the ReLUIS 2019–2021 research project (Network of the University Laboratories of Seismic Engineering) supported by the Civil Protection Department (DPC), the Work Package WP4 “Seismic Risk and Damage Maps at National scale—MARS” aimed to update the 2018 version of the National Risk Assessment (NRA). One of the goals of the WP4—MARS was to collect, analyse and upgrade loss models to estimate direct economic losses, unusable buildings and casualties (Task 4.4—“Risk: evaluation of consequences and economic losses”). Task 4.4 aimed to carry out a critical review of the models available in the literature and subsequently specific comparisons to better understand the capability and reliability of the different models, in particular those adopted to calculate the seismic losses in the 2018 NRA. Furthermore, the derivation of new models in order to improve the results of the previous study was another goal of the project. The paper focuses on the assessment and calibration of models and tools to derive human casualties (deaths and injured) and usability rating as well as repair costs and population assistance costs associated with residential buildings damaged by seismic actions. In detail, the available literature on Casualty Estimation Models (CEMs) is analysed, and an updated model is calibrated to estimate human casualties for the Italian context. The model emphasises a relationship between the casualties and the severity of the damage. A strong correlation exists between the post-earthquake usability of buildings, damage state (DS), repair costs and time required to assist the population. According to data collected in the reconstruction processes of recent Italian earthquakes, fragility curves in terms of loss-of-usability for partially unusable and unusable buildings and the correlation between usability ratings (immediately available post-earthquake) and DS (easily computable by using existing empirical- or mechanical-based fragility functions) are defined. Finally, consequence functions able to associate direct costs (repair costs) and indirect costs (population assistance) have been calibrated as a function of buildings’ usability or damage state.
