“…This scale involves five damage levels, i.e., slight damage (D1), moderate damage (D2), extensive damage (D3), complete damage (D4), and collapse (D5). The relationship between damage level and limit state was defined using observed damage data in a series of recent Italian earthquakes beginning in 1976 with the Friuli event through to 2002 with the Emilia event (Faravelli et al, 2017). According to the EMS98 scale, D4 and D5 refer to building states defined as completely damaged and collapsed, respectively, and thus are clearly well beyond a state in which they can be considered usable.…”

A resilience-based method for prioritizing post-event building inspections

Despite the wide range of possible scenarios in the aftermath of a disruptive event, each community can make choices to improve its resilience, or its ability to bounce back. A resilient community is one that has prepared for, and can thus absorb, recover from, and adapt to the disruptive event. One important aspect of the recovery phase is assessing the extent of the damage in the built environment through post-event building inspections. In this paper, we develop and demonstrate a resilience-based methodology intended to support rapid post-event decision-making about inspection priorities with limited information. The method uses the basic characteristics of the building stock in a community (floor area, number of stories, type of construction and configuration) to assign structure-specific fragility functions to each building. For an event with a given seismic intensity, the probability of each building reaching a particular damage state is determined, and is used to predict the actual building states and priorities for inspection. Losses are computed based on building usage category, estimated inspection costs, the consequences of erroneous decisions, and the potential for unnecessary restrictions in access. The aim is to provide a means for a community to make rapid cost-based decisions related to inspection of their building inventory. We pose the decision problem as an integer optimization problem that attempts to minimize the expected loss to the community. The advantages of this approach are that it: (i) is simple, (ii) requires minimal inventory data, (iii) is easily scalable, and (iv) does not require significant computing power. Use of this approach before the hazard event can also provide a community with the means to plan and allocate resources in advance of an event to achieve the desirable resiliency goals of the community.

“…Over several years, Eucentre has also been developing tools implemented in WebGIS platforms for the assessment of seismic risk and damage scenario. These platforms consider residential buildings [10,11], school buildings [10,11,12], transportation network infrastructures [10,13] and dams [14,15] as vulnerable elements. Recently, also hospitals have been taken into account.…”

Eucentre has developed a platform addressed to the scientific community in which different research groups can share data, methods and models to evaluate the seismic risk of Italian territory. In the platform, called IRMA (Italian Risk MAps), there are different tabs and tools that allow producing seismic risk maps and damage scenarios with OpenQuake. OpenQuake is a calculation engine that has been recently developed as part of the Global Earthquake Model (GEM) (http://www.globalquakemodel.org) to evaluate the earthquake loss estimation. To perform earthquake damage scenario or risk calculations, in the platform IRMA the user can either create or upload different exposure/vulnerability databases as well as different sets of fragility curves. The hazard is fixed and it is the MPS04 hazard model, developed by INGV
