Çelik Kiriş ve Kolon Plastik Mafsal Parametrelerinin ve Şekil Değiştirme Sınır Değerlerinin Karşılaştırmalı İncelenmesi

Mustafa Berker ALICIOĞLU

Abstract: Yapılardaki deprem hasarının tahmini, can ve mal kaybını önleme açısından oldukça önemlidir. Hasar tahmini, plastik mafsal parametrelerinin ve şekil değiştirme sınır durumlarının gerçek yapı davranışını yansıtması oranında başarılı olmaktadır. Yapı tasarımında ve mevcut yapı değerlendirmesinde çeşitli standartlar ile plastik mafsal parametreleri ve şekil değiştirme sınır değerleri belirlenmiştir. Federal Acil Durum Yönetim Kurumu (FEMA) ve Amerikan İnşaat Mühendisleri Birliği (ASCE) bu alanda öncü olmuşlardır.… Show more

On 6 February 2023, two very large destructive earthquakes occurred in the East Anatolian Fault Zone (EAFZ), one of Türkiye’s primary tectonic members. The fact that these earthquakes occurred on the same day and in the same region increased the extent of the destruction. Within the scope of this study, twenty different settlements affected by earthquakes and located directly on the EAFZ were taken into consideration. Significant destruction and structural failure at different levels were induced in reinforced concrete (RC) structures, the dominant urban building stock in these regions. To determine whether the earthquake hazard is adequately represented, the PGA values predicted in the last two earthquake hazard maps used in Türkiye for these settlements were compared with the measured PGAs from actual earthquakes. Subsequently, the damage to reinforced concrete structures in these settlements was evaluated within the scope of construction and earthquake engineering. In the final part of the study, static pushover analyses were performed on a selected example of a reinforced concrete building model, and target displacement values for different performance levels were determined separately for each earthquake. For the 20 different settlements considered, the displacements were also derived based on the values predicted in the last two earthquake hazard maps, and comparisons were made. While the target displacements were exceeded in some settlements, there was no exceedance in the other settlements. The realistic presentation of earthquake hazards will enable the mentioned displacements predicted for different performance levels of structures to be determined in a much more realistic manner. As a result, the performance grades predicted for the structures will be estimated more accurately.
