Abstract. Modelling the seismic potential of active faults and associated epistemic uncertainty is a fundamental step probabilistic hazard assessment (PSHA). We use SHERIFS (Seismic Hazard Earthquake Rate In Fault Systems), an open-source code allowing us to build models including earthquake ruptures involving several faults, model seismicity rates on North Anatolian (NAF) system in Marmara Reg...

The influence of the effects degradation materials on seismic fragility Cultural Heritage buildings in Granada (Spain) is investigated. material, which mainly happens at lower levels façades, obtained by using 3D photogrammetry data. Fragility curves for three cultural heritage constructions are calculated FE nonlinear dynamic analyses both non-deteriorated and deteriorated geometries. Finite E...

In the present paper, the focus is on the evaluation of steel dual-system frame buildings using four main types of structural analysis (Linear Static, Linear Dynamic, Nonlinear Static and Nonlinear Dynamic Analyses) with regard to "Seismic Rehabilitation Code for Existing Buildings in Iran" (based on FEMA 273 and 356) where the first two authors of the article tend to follow the previous work (...

This study presents an updated attenuation model to predict the peak ground acceleration (PGA), velocity (PGV), 5% damped pseudo-spectral (SA), and average spectral (AvgSA) at hill zone of Mexico City for interface earthquakes. The strong-motion dataset comprises 33 earthquakes recorded CU station, covering a moment magnitude (Mw) range from 6.0 8.1 source-to-site distance (Rrup) 240 490 km. Gi...

This report addresses the broad role of aftershocks in the Performance-based Earthquake Engineering (PBEE) process. This is an area which has, to date, not received careful scrutiny nor explicit quantitative analysis. We begin by introducing Aftershock Probabilistic Seismic Hazard Analysis (APSHA). APSHA, similar to conventional mainshock PSHA, is a procedure to characterize the timevarying aft...

A new two-step approach is proposed to quantify the uncertainties of the seismicity rate ν(M) estimated by Gutenberg-Richter relations of seismic area source zones in logic tree-driven probabilistic seismic hazard analysis. The first step makes use of the possibility that the uncertainties of the Gutenberg-Richter parameters α and β (or a and b), expressed by their covariance matrix C(α, β) (or...

Probabilistic seismic hazard analysis [PSHA, e.g., Cornell (1968); Anderson and Trifunac (1978); McGuire (1977); McGuire (1995)], typically used in risk assessment and hazard mitigation, has so far relied on ground motion prediction equations (GMPEs), also called attenuation relations [e.g., the next generation attenuation relations or NGA by Campbell and Bozorgnia (2008); Chiou and Youngs (200...

Batubesi Dam which is located in Sorowako region in the middle part of Sulawesi island had been designed with seismic coefficient about 0.20g. The region constitutes an active earthquake zone with the recurrence frequency and magnitude of the earthquake are relatively high. The region is located on and active fault zone due to lateral fault movement (strike-slip) of Matano fault, Palukoro fault...
