Correlations of Ground-Motion Intensity Measures Observed in the Turkish Strong-Motion Database Ertuğrul, Zehra (2025-10-01) This study aims to develop correlation models for ground-motion intensity measures based on the Turkish strong-motion data. The intensity measures under examination are horizontal spectral accelerations (SAs) with periods ...
Comparison of Probabilistic Fault Displacement Hazard Assessment Results with Observed Permanent Ground Displacements in the Aftermath of the 6 February 2023 Kahramanmaraş Türkiye Earthquakes. Ertuğrul, Zehra (2024-04-14) Normal 0 false false false EN-GB X-NONE X-NONE ...
VS Profiles for Turkey Şen, Ali Cemil; Ertuğrul, Zehra (2024-01-01) The Disaster and Emergency Management Authority of Turkey is currently operating 850 strong-motion stations throughout the country. At 112 of 850 station sites, variation of shear-wave velocity (VS) with depth was measured...
1D reference V-S profiles compatible with ground-motion prediction equations developed for Turkey Ertuğrul, Zehra (2023-03-01) V-S30, time-averaged shear-wave velocity over the top 30 m of the site profile is the parameter that mainly governs site response functions in ground-motion prediction equations (GMPEs). Although the use of V-S30 as a main...
SENSITIVITY ANALYSIS FOR DERIVATION OF 1D VS PROFILES USING INVERSE QUARTER-WAVELENGTH THEORY Ozisin, Mehmet; Ertuğrul, Zehra (2023-01-01) It is possible to convert median response spectra estimated based on a selected Ground-motion Prediction Equation (GMPE) to its corresponding Fourier amplitude spectrum (FAS) by using the inverse vibration theory (IRVT). T...
Assessment of Aleatory and Epistemic Uncertainty for Ground-Motion Intensity Measure Prediction in Turkey Ertuğrul, Zehra (2019-02-01) In this study, we quantify the reduction in total sigma (sigma(total)) of the Turkish ground-motion predictive models by partially removing the ergodic assumption. By partitioning residuals into four components: repeatable...
Advantages of industry-academia partnerships for the development of professional competences in civil engineering Akan, Onur Deniz; Bilgin, Gizem; Ertuğrul, Zehra (2018-01-01) The Civil Engineering undergraduate program offered by the Department of Civil Engineering of TED University – Turkey, in realization of the necessity to enhance both technical and transversal competencies of its students,...
Seismic behaviour of the old-type gravity load designed deteriorated RC buildings in Cyprus Safkan, Ismail; Sensoy, Serhan; Ertuğrul, Zehra (2017-12-01) Corrosion related deterioration of reinforced concrete buildings is often studied by the structural engineering community. The literature reveals the fact that modelling of deteriorated members requires a unique considerat...
A model for predicting vertical component peak ground acceleration (PGA), peak ground velocity (PGV), and 5% damped pseudospectral acceleration (PSA) for Europe and the Middle East Ertuğrul, Zehra; Kale, Ozkan; SANDIKKAYA, MUSTAFA ABDULLAH (2017-07-01) In this study, we present a ground-motion model for the vertical component of peak ground acceleration, peak ground velocity, and 5% damped pseudo acceleration response spectra at periods ranging from 0.01 to 4 s. The vert...
Single station sigma for Turkish strong motion stations Akkar, Sinan; Ertuğrul, Zehra (2017-01-01) As ground motion observations over long enough time periods are unavailable for majority of sites, most of the ground motion prediction equations have been derived using observed data from multiple stations and seismic sou...
