“…Moreover, for buildings with irregularities highly affecting the seismic behavior, the method proposed could lead to a wrong estimation of the seismic capacity. Of course, a more refined and time-consuming modelling strategy of each individual building could improve the final result, however, it would require the deep knowledge of the geometrical and material characteristics of them (Belleri et al 2015;Nastri et al 2017;Dal Lago and Ferrara 2018;Magliulo et al 2018;Bovo and Savoia 2018;Bovo and Savoia 2019;Dal Lago et al 2019;Brunesi et al 2020;Soydan et al 2020), and it could be not appropriate for a large-scale seismic damage assessment.…”

In May 2012, two strong earthquakes hit the northern Italy revealing the significant seismic vulnerability of precast reinforced concrete structures and causing severe damage and many collapses, and high economic losses. After the lesson learnt from these events, more reliable seismic design criteria have been established for the design of new structures and different approaches have been proposed for the seismic assessment of the existing structures. In this context, the paper presents the results of a first application of the PRESSAFE-disp method, recently proposed by the authors, allowing to define the fragility curves of precast RC buildings at various limit states, including collapse. A stock of 91 precast buildings in the industrial area of San Felice sul Panaro (Modena) was selected as a benchmark case study to verify the reliability of the method in assessing seismic damage scenarios. In particular, with reference to the 2012 seismic ground-motion, two large-scale stochastic models are outlined to predict the number of the buildings collapsed in the area. The first one is based on a Monte Carlo simulation which incorporates the evaluation of the uncertainties, while the second one is a direct simplified calculation. Comparative considerations on the outcomes of the two methods for different seismic intensities are discussed, including the directionality effect of the ground-motion. To test the soundness of the simulations, the results of the two methods are compared with the real data collected through in-situ surveys. The procedures proposed here result, on average, in good agreement with the observed damage scenario. It is worth noting that, due to the inherent simplicity of the methods, they could be implemented to perform scenario-based seismic loss assessments to estimate the financial consequences of an earthquake affecting one or more industrial areas, and to drive the decision-making process for the seismic retrofit of existing precast RC buildings.

“…Hence, it was also utilized in some base isolation systems [10][11][12]. Lead extrusion damper (LED) which is a passive EDD also benefits from the metallurgical properties of lead [13][14][15][16][17][18][19]. LED dissipates the energy by extrusion of lead through a hole or an orifice.…”

“…The rationale of the study is the development of a three-dimensional detailed finite element model of LEDs that were tested (T-LED), [13][14][15][16][17][18][19], and studied in the literature (L-LED), [21][22]. To this extent, numerically obtained force-displacement hysteresis of T-LED and the maximum force of L-LED were compared with the related experimental results.…”

A significant amount of seismic energy is imparted to the structures during earthquakes. The energy spreads within the structure and transforms in various energy forms as dissipated through the structure. The conventional seismic design provides specific ductile regions, namely plastic hinges, on structural elements. Therefore, the energy dissipation capacities of the structural elements and the structure enhance. However, this approach accepts that the deformations will concentrate on the plastic hinge zones and severe damage may occur on structural elements within deformation limits that are defined by the seismic codes. The modern seismic design aims to dissipate a large portion of the seismic input energy by installing energy dissipating devices (EDDs) to the structure. Thus, deformation concentrates on EDDs which can be replaced after an earthquake, and energy demand for structural elements is decreased. Lead extrusion damper (LED) is a passive EDD that utilizes the hysteretic behavior of lead. In this paper, the preliminary results of the developed three-dimensional finite element model (FEM) for a LED is presented. The results obtained from the finite element analysis (FEA) were compared with the experimental ones in which LEDs were exposed to sinusoidal displacements. Also, the applicability of the developed FEM was checked for different component dimensions given in the literature. The comparison study yielded a satisfactory consistency. Additionally, the maximum relative difference obtained for the literature devices was reduced to 12% from 39% by the developed FEM.

Buildings have a central role to play in the energy transition driven by the European Commission with the introduction of the nearly zero-energy buildings notion for both new constructions and existing building stocks. Despite the growing interest in improving the energy performance of residential as well as office buildings, a research gap is identified in the field of the renovation of industrial buildings and facilities in terms of energy efficiency. A lack is recognized in terms of analysing the improvement of the work environment in all the areas that are not used as offices. Common decarbonisation strategies are usually adopted, as the electrification of some processes, the replacement of obsolete machinery or the implementation of renewable energy sources. However, reaching the ambitious levels set by the Energy Performance of Buildings Directive which aims at nearly zero-energy buildings, remains a challenge. The present paper aims to analyse the main barriers that hamper the development of highly energy efficient and decarbonised buildings in the productive sector and the effective deep energy renovations of industrial facilities. Moreover, it intends to highlight alternative strategies and opportunities and to underline potential benefits.
