Abstract This study focuses on the seismic safety evaluation of masonry buildings in Turkey for in‐plane failure modes using fragility curves. Masonry are classified and a set curves generated each class. The major structural parameters classification considered as number stories, load‐bearing wall material, regularity plan arrangement walls (required length, openings walls, etc.), accordance with observations from previous earthquakes field databases. by time history (for demand) pushover...
On 6 February 2023, two earthquakes occurred approximately 9 h apart, with Mw 7.8 and 7.5, epicenters located in Pazarcık Elbistan districts of Kahramanmaras province, respectively. As part a national project team which was funded by the Disaster Emergency Management Presidency Turkiye (AFAD) between June 2021 authors this article had proposed framework to assess seismic resilience an urban region. The pilot area small-scale industrial town named Turkoglu south Kahramanmaras, at intersection...

Abstract The time-averaged shear-wave velocity in the upper 30 m of a site (VS30) is virtually essential characterizing local soil conditions for multiple purposes, including estimation effects, anticipated ground-motion levels, seismic hazards, and shape design spectra. Considering significance this proxy that number Disaster Emergency Management Presidency Türkiye (AFAD) strong stations across lack assigned VS30 values, comprehensive study was performed herein to develop empirical...
This study proposes a hybrid modeling approach for the seismic performance assessment of unreinforced masonry buildings. The method combines finite-element and equivalent-frame approaches such that more powerful features each are utilized. is used to model components different geometrical material characteristics with high level accuracy. Then this numerically simulated database in analytical buildings equivalent beams columns instead spandrels piers. Thus it becomes possible building as...
Seismic vulnerability assessment of residential buildings in regions high seismicity is an interdisciplinary problem requiring major inputs from fields seismology and earthquake engineering. The basic two components loss estimation methods are information on regional building stock. This study presents a realistic methodology where the first component, input ground motions, obtained ground-motion simulations using stochastic finite-fault technique. second information, other hand, taken into...
In this study, seismic safety of low–rise and mid–rise structures, which constitute approximately 75% the total building stock in Turkey, is investigated by generating fragility curves. The scope 3, 5, 7, 9–story reinforced concrete moment resisting frame structures. uncertainties material variability specific characteristics construction practice Turkey are taken into account formation structural simulations. Two-dimensional analytical models constructed accordingly categorized as poor,...
Unreinforced and non-engineered masonry buildings are highly vulnerable to seismic hazard constitute a significant percentage of earthquake losses, including both casualties economic losses. This study presents an engineering application on safety assessment unreinforced (URM) in Istanbul, Turkey, metropolitan city under very high risk. Nearly 20,000 were examined through two-stage procedure order identify the addresses those which Furthermore, obtained database can be employed preparation...
Following a disaster or an emergency situation (e.g., earthquake,) in facility, it is crucial for response teams to rapidly access navigation information of the its contents and final status facility damages vulnerable locations). However, current practice, accessing these items time-consuming accessed incomplete, since there are multiple sources that mostly disorganized. This study proposes Building Information Model (BIM) based approach integrated with sensors provide damage vulnerability...
Seismic loss estimation studies require fragility curves which are usually derived using ground motion datasets. Ground records can be either in the form of recorded or simulated time histories compatible with regional seismicity. The main purpose this study is to investigate use alternative datasets (simulated and real) on curves. Simulated dataset prepared considering seismicity parameters corresponding Erzincan stochastic finite-fault technique. In addition, regionally chosen from...
This research performs a parametric study based on Equivalent Single Degree of Freedom (ESDOF) models for simplified seismic analysis unreinforced masonry (URM) structures. is necessary action due to the fact that it not affordable model and analyze populations buildings by using detailed continuum-based during regional damage loss estimation studies. Hence, this focuses sensitivity major structural parameters selected idealized hysteretic URM buildings. The numerical are subjected...
Electric power is essential in post-earthquake periods for the continuous functionality of disaster management and emergency services. In addition, interruption electric can cause significant economic losses due to downtime critical facilities. Therefore, it very important maintain seismic safety systems components. There are existing regulations standards regarding systems, especially United States America (USA) Europe. A similar regulation has been prepared recently Türkiye, which a...
The paper is concerned with loss estimation analysis of flat-slab structures, a reinforced concrete structural form that exhibits behavior and response patterns distinct from conventional moment frames. fragility information obtained for structures presented in companion implemented into HAZUS, the assessment software Federal Emergency Management Agency. latter program includes many existing types, but does not deal structures. For implementation purposes, curves should be format consistent...
Inelastic displacements of reinforced concrete systems are investigated by employing an energy-based approach. A hysteresis model is developed that accounts for stiffness degradation, strength deterioration and pinching. The calibrated using experimental data from literature. displacement ratios calculated under a specific set ground motion records with long effective durations. results reveal the importance deteriorating behavior duration excitations, especially short medium period...
