Seismic risk assessment using updated hazard and building inventory data

Abstract

Seismic risk assessment using updated hazard and building inventory dataThis study focuses on the assessment of potential seismic impacts from two active segments of the North Anatolian Fault running across the Sea of Marmara. Two seismic scenarios with moment magnitudes of Mw 6.9 and Mw 6.7 were developed for individual segment rupture, and the third one with the magnitude of M w 7.2 was developed for simultaneous activation of both segments. 15,871 existing buildings were grouped into 10 main classes. Each class was assigned a respective capacity curve and a set of fragility curves that determine the probability of exceeding one of the following five damage states: none, slight, moderate, extensive, and complete.

Seismic risk for Croatia: overview of research activities and present assessments with guidelines for the future

“…In addition, although this is not specially emphasized, the standard vulnerability curve definition process is most often reduced to analyses of an idealised of systems with a single degree of freedom which can, from the engineering standpoint, hardly be applied to complex structural systems. This has recently been confirmed by the results of detailed experimental and numerical analyses for selected typical buildings in the city of Zagreb [64,65]. In fact, these results point to frequent deviations with respect to the preliminary assessments with simplified methods/models.…”

Integrated disaster matrix and vulnerability index analyze the seismic performance of typical structures in rural villages in historical earthquakes

“…In this paper, the historical disaster data are reviewed and the earthquake disaster matrix is established. Based on the seismic site survey data (Lourenço, 2002), five states of structural damage were determined: Basically intact, Minor, Medium, Serious, and Collapse (Pakdamar & Lourenço, 2019). Based on the rapid analysis method of building earthquake vulnerability, the historical seismic disaster data are studied retrospectively and the historical earthquake disaster matrix is established.…”
