Seismic Risk Assessment in the Attica Basin

“…The main difference between this methodology and the aforementioned is that the latter is far more customizable and versatile, as the layers of input information can be adjusted to the user's requirements, data availability and desired outcome. Such methodologies have been applied in various cities around the world such as Barcelona (Lantada et al, 2003), Brussels (Petermans et al, 2006), Thessaloniki (Pitilakis et al, 2006), Grenoble (Gueguen et al, 2007), Chania (Sarris et al, 2010) and Tabriz (Karimzadeh et al, 2014). Justification for this selection will be provided in the Materials and Methods chapter.…”

Seismic response of an 8-story RC-building from ambient vibration analysis

“…Operational Modal Analysis (OMA) is generally preferred to forced vibration measurements due to the fact that the same modal parameters can be obtained from vibration data in operational rather than laboratory conditions (Reynders, 2012). There are several studies that have used ambient vibration testing for the identification of the dynamic behavior of civil engineering structures (Brownjohn, 2003;Ventura et al, 2003), finite element calibration and updating (Teughels, 2003;Jaishi and Ren, 2005), vulnerability assessment (Guéguen et al, 2007;Michel et al, 2008;Michel et al, 2012) and damage detection (Peeters, 2000).…”

A support vector regression approach for building seismic vulnerability assessment and evaluation from remote sensing and in-situ data

“…Vulnerability of a hazard can be defined by a mixture of different components including physical, demographic, social, economic, ecological and political aspects. Several methodologies have been developed as a function of the possible resources (Material type, building location and foundation, age of construction, type of roof, plan regularity, elevation regularity,position of the structure in the block) and the scale (several hundred of buildings, several buildings, individual buildings) of vulnerability assessment [1]. In this framework, remote sensing can effectively contribute by providing building attributes related to seismic vulnerability in a large scale This work has been supported by the ANR national research agency as part of its RiskNat program (URBASIS project, no.…”

“…Polli in a recent work [4] for seismic vulnerability assessment attempt extraction of required parameters through analysis of very high resolution remote sensing images. In addition several engineers and researchers in seismic risk domain have been taking into account different parameters in order to measure seismic vulnerability, such as: Material type, building location and foundation, age of construction, type of roof, plan regularity, elevation regularity [1]. It has been proved that existing approaches for assessing seismic vulnerability are sufficient but can be very time consuming due to the high computational costs especially for large scale urban areas.…”

“…Figure 2 shows an area of the overall VHR orthoimage The available in-situ data correspond to residential buildings belong in the same geographical urban area with the remote sensing data. This information is seismic vulnerability indicators, estimated by experts [1].…”
