Damage scenario for L’Aquila area: a large-scale comparison with 7597 RC buildings post-earthquake data
No full textMethods for seismic vulnerability assessment are a fundamentally important tool for the identification and delimitation of seismic-prone areas and to plan seismic risk reduction and management strategies. They allow the derivation of event scenarios describing the expected consequences of the event, leading to estimates of people involved, dead or injured; damage to facilities and structures; and the number of unusable buildings and homeless people.
In present work, a simplified mechanical method – PushOver on Shear Type models (POST) – for seismic vulnerability assessment of infilled RC building is briefly recalled (Del Gaudio et al., 2015; Del Gaudio et al., 2016a; Del Gaudio et al., 2017). The methodology allows the definition of building structural characteristic through a simulated design procedure in compliance with design code prescriptions, professional practice and seismic classification of the area of interest at the time of construction. The evaluation of non-linear static response is performed through a simplified model, considering the contribution of both RC columns and infill panels to lateral resistance, based on Shear Type assumption. Seismic capacity assessment is made in the SPO2IDA framework (Vamvatsikos and Cornell, 2006) for different performance levels, defined according to the damage classification proposed by European Macroseismic Scale (Grünthal, 1998). Finally, the use of a Monte Carlo simulation approach allows the derivation of fragility curves for different damage states (DSs).
Therefore, predicted damage scenario is derived from POST methodology for a database consisting of 7597 Moment Resisting Frame (MRF) residential RC buildings located in the Abruzzi region, which after the 2009 catastrophic earthquake have been charged to post-earthquake usability assessment procedure (Del Gaudio et al., 2016b). Predicted damage scenario is then compared with damage scenario based on post-earthquake data

No full textInfluence of construction age on seismic vulnerability of masonry buildings damaged after 2009 L'Aquila earthquake
No full textThe aim of this study is to describe the evolution of vulnerability over the years for masonry buildings characterized by a good quality layout and/or a regular texture. To this aim, data collected shortly afterwards the L'Aquila 2009 earthquake are considered, recently released by the Italian Department of Civil Protection (DPC) through the Da.D.O. (Database di Danno Osservato, Database of Observed Damage) platform (Dolce et al., 2019) [1]. The taxonomy has been defined reflecting the need to consider all the parameters available from post-earthquake inspections and the obtainment of reliable and homogeneous sample. A time-consuming data processing has been performed to obtain a generalized version of the original database, which has been integrated with census data to avoid bias in vulnerability analysis. Then, damage analysis has been done considering 5 + 1 damage grades defined for the whole building based on the conversion of damage for vertical structures in sight of the classification of European Macroseismic Scale. The analysis of mean damage values reveals the general trends as a function of the main influential parameters, i.e. construction age and horizontal structural types, having fixed the vertical structural type and the quality layout. Vulnerability curves were derived assuming a lognormal statistical model and peak ground acceleration as intensity measure, through a minimization procedure of the distance between predicted and observed mean damage. In addition, the general criteria established to define the taxonomy had allowed to accomplish a direct comparison also between vertical structures, namely buildings with good quality and regular texture analysed herein and those with bad quality and irregular layout thoroughly analysed in Del Gaudio et al. (2021) [2]; fully characterizing the behaviour of masonry buildings under lateral loads
La “missione di civiltà” del diritto sociale europeo e il nuovo assetto dei licenziamenti collettivi in Italia : rileggendo Mario Grandi
No full textIl contributo trae ispirazione da un’osservazione del Prof. Mario Grandi, che, in un saggio del 2007, sottolineava come il diritto sociale europeo, muovendo «nella direzione della promozione di mercati del lavoro flessibili e inclusivi», svolgesse un’essenziale «missione di civiltà», consistente nella difesa e promozione della persona nel lavoro. Nel cono d’ombra del diritto del lavoro europeo rientra la normativa nazionale in materia di licenziamenti collettivi, la quale è stata di recente interessata, in una fase di generale ripensamento (o, se vogliamo, di affievolimento) delle garanzie in punto di stabilità del rapporto di lavoro, da significative variazioni, che hanno investito tanto il profilo procedurale quanto quello rimediale, ingenerando dubbi di compatibilità con il quadro euro-unitario. Lo scopo del presente scritto è quindi di sondare la
coerenza dell’attuale assetto della disciplina del licenziamento collettivo in Italia con la “missione” della direttiva 98/59/CE, previa messa a fuoco degli interessi (individuali e/o collettivi) protetti e degli strumenti (sostanziali e/o processuali) contemplati da quest’ultima.This article takes inspiration from an observation made by Professor Mario Grandi, who, in an article written in 2007, argued that European Social Law, aiming at «promoting flexible and inclusive labour markets», carried out an essential «civilizing mission», consisting in defending and promoting people at work. The national rules on collective redundancy fall within the scope of European Social Law. The Italian framework has recently been affected, in a period of overall revision (or, maybe, mitigation) of the system in terms of job security, by significant changes, which have addressed both the procedural and the remedial profiles of the regulation, generating several doubts in terms of compatibility with the European legal framework. The aim of this article is thus to investigate the coherence of the existing Italian collective redundancy legal framework with the “mission” of dir. 98/59/CE, after clarifying which are the interests protected (individual and/or collective) and the instruments (substantial and/or procedural) envisioned by the applicable directive
