On 6 February 2023, two independent earthquake pairs on the East Anatolian Fault Zone, with epicenters in Pazarcık (Mw = 7.7) and Elbistan 7.6) districts of Kahramanmaraş province, caused great destruction. Adıyaman Gölbaşı this city are among settlements most affected by earthquake. Especially district where geotechnical damages observed, destructive effects earthquakes have been clearly observed buildings different structural systems. In study, information is given about that hit region...

The 6th February 2023 Pazarcık and Elbistan earthquakes (Mw = 7.7 Mw 7.6) caused great destruction in many cities were the disaster of century for Türkiye. greatest was provinces Hatay, Kahramanmaraş, Adıyaman during these earthquakes, which independent each other occurred on same day. Information about strong ground motion records is given within scope this study. Reinforced concrete (RC) structures constitute a large part urban building stock earthquake region exposed to structural damage...

In parallel with the increase in vehicle sales worldwide, waste tires are becoming an increasing problem. The storage and disposal of these critical environmental problems. Re-using wastes different areas instead being disposed is vital preventing pollution creating new low-cost products. From this motivation, paper investigates properties traditional reinforced-concrete beam recycled steel wires (RSWT) obtained from tires. RSWT were added to between 1% 3% by weight increment 1%. total, 9...

Determining the risk priorities for building stock in highly seismic-prone regions and making final decisions about buildings is one of essential precautionary measures that needs to be taken before earthquake. This study aims develop an Artificial Neural Network (ANN)-based model predict reinforced-concrete (RC) constitute a large part existing stock. For this purpose, network parameters structure have been optimized by establishing hybrid with Genetic Algorithm (GA). As result, ANN can...

Many reinforced-concrete structures collapsed or were seriously damaged in the 7.7 and 7.6 magnitude earthquakes that occurred southern Türkiye on 6 February 2023. The recorded peak ground accelerations quite high (2.2 g) motions’ elastic acceleration response spectra significantly greater than design given by most recent Turkish seismic code. A total of 518,000 houses heavily eleven cities affected earthquake. More 53,000 people lost their lives over 100,000 injured, majority these injurits...

On 6 February 2023, two large earthquakes struck southern Türkiye on the same day, resulting in a considerable loss of life and property damage over region that included 11 cities. After these disasters, there was requirement to define soil-related intensity distribution, aside from manufacturing defects caused by buildings. The modified Mercalli (MMI) scale results value (XI) when decimal values are not mathematically considered, even though fundamental data AFAD USGS sources differ. In...

The Kahramanmaraş (Türkiye) earthquake on 6 February 2023, one of the largest earthquakes century, caused collapse or severe damage thousands structures. This catastrophic disaster resulted in over 53,000 fatalities and rendered many structures unusable. study addresses observed reinforced concrete (RC) structures, which constituted majority existing urban building stock. In this study, firstly, information about destructive was given. predicted PGAs last two hazard maps used Türkiye were...

Bitlis has hosted many civilizations and is located in Turkey’s significant strategic transit corridor. Many historical structures belong to different cultures the city. The structural analysis of five minarets mentioned folk songs brand value city terms buildings subject this study. These are precious because they witness important events Non-destructive test methods determined material properties stone used constructing minarets. Within scope study, detailed information about each minaret...

In this study, basalt, which is common around Diyarbakır province (Turkey), used as concrete aggregate, waste materials mineral additives and Portland cement binding material to prepare mixes. This paper aims determine the proper admixture levels usability of basalt in mixtures based on mechanical, physical chemical tests. Thus, order strength durability performance with 72 sample cubes 150 mm were prepared three groups: mineral-free (MFA), 10% amount substituted for silica fume (SFS) 20%...

Minarets are slender and tall structures that built from different types of materials. Modern materials also starting to be used in such with the recent developments material technology. The seismic vulnerability dynamic behavior minarets can vary, depending on characteristics. Within this study’s scope, thirteen Türkiye were chosen as variables. A sample minaret model was an example nine heights reveal how characteristic change affects behavior. Information mechanical characteristics given...

The realistic determination of damage estimation and building performance depends on target displacements in performance-based earthquake engineering. In this study, were obtained by performing pushover analysis for a sample reinforced-concrete model, taking into account 60 different peak ground accelerations each the five stories. Three estimation, such as limitation (DL), significant (SD), near collapse (NC), acceleration numbers stories, respectively. It aims to develop an artificial...

Huge losses of life and property occurred as a result two independent catastrophic earthquakes on 6 February 2023 in the Eastern Anatolian Fault Zone, where no significant earthquake has approximately 500 years. The earthquakes, whose epicenters were Pazarcık Elbistan districts Kahramanmaraş province at 9 h intervals, had magnitudes Mw = 7.7 7.6 caused different levels structural damage, especially masonry-style structures rural areas. In this study, damage that masonry village schools,...

The Marmara Region (NW Turkey) has experienced significant earthquakes (M > 7.0) to date. A destructive earthquake is also expected in the region. To determine effect of specific design spectrum, eleven provinces located region were chosen according Turkey Earthquake Building Code updated 2019. Additionally, differences between previous and regulations country investigated. Peak Ground Acceleration (PGA) Velocity (PGV) obtained for each province by using ground motion levels with 2%, 10%,...

Masonry structures began to be built with the existence of human beings and are an inspiration for today’s structures. Monumental historical buildings according people’s religious beliefs have special importance among such Despite being exposed many natural disasters over time, that survived till today indispensable part heritage. Within scope this study, structural analyses were carried out Ulu Mosque’s minaret in Bitlis (Turkey), located Van Lake basin, using both on-site measurements...

The loss of life due to large-scale structural damage has again demonstrated the importance taking precautions before an earthquake. In this context, determining risk priorities for existing building stock and making final decisions about buildings is one basic measures be taken Within scope study, regional have been determined twenty different masonry in Bitlis (Türkiye), located Lake Van Basin, which a high earthquake risk. Turkish Rapid Assessment Method was used structures study updated...

Seismic-induced damages in reinforced-concrete (RC) buildings were primarily associated with materials' low strength and poor properties.This study aims to investigate the seismic response of RC structures according different material's design spectra.Adaptive static pushover eigenvalue analysis performed for four spectra, five types concrete, two reinforcement grades.Four spectra obtained by considering discrete geographical locations earthquake risks via updated Turkish Earthquake Hazard...

Many factors affect the earthquake vulnerability of reinforced concrete (RC) structures, constituting a large part existing building stock. Short column in RC structures is one reasons for damage. Significant damages may occur due to brittle fractures structural elements when shear resistances are exceeded under effect high stress short columns formed architectural and topographic reasons. This study created models three situations: hill slope effect, band-type window mezzanine floor, which...
