Özet:

 The destructive effects of earthquakes in our country, especially on existing structures, have focused on the evaluation and strengthening of the earthquake performance of the existing structures. The decision of either strengthening or demolition of the existing structures requires performance evaluation tests. Additionally, the use of change of the buildings can requires performance tests. In this study, an additional story was planned to be constructed on a four story building, which was originally designed as a student dormitory then revised to be used as a hotel. The additional story was designed to be accommodate the maximum rooms counts, and two different structural systems was considered using steel and concrete. The performance of the existing building with and without additional story was investigated under earthquake loads according to the TBDY Turkey building earthquake code 2018. Structural periods, story drifts, performance curves, plastic hinge formations and possible damage levels for the two different models were compared with each other. The results showed that both additional stories were produced similar number of deficient structural members on the base structure in terms of the structural load capacities. On the other hand, the amount of plastic hinges and story drifts reduced up to 15.22 and 37.8 for additional steel story, respectively.

 Ülkemizde yaşanan depremlerin özellikle mevcut yapılar üzerindeki yıkıcı etkileri, bu yapıların deprem performansının en doğru şekilde değerlendirilmesini gerekli kılmaktadır. Yapının güçlendirilmesi veya yıkılması kararı yapısal performans değerlendirme çalışmalarını odak noktası haline getirmiştir. Bununla birlikte yapının kullanım amacında meydana gelecek farklılıklar ve ek yapılar yine mevcut yapısal performans değerlendirme analizlerini gerektirmektedir. Yapılan araştırma kapsamında öğrenci yurdu olarak tasarlanmış daha sonrasında konaklama evi olarak kullanılmaya devam etmekte olan mevcut 4 katlı betonarme bir yapıya ek 1 kat yapılması planlanmaktadır. Bu çalışmada ek kat mimari açıdan en fazla oda barındıracak şekilde tasarlanmış ve taşıyıcı sistemi çelik ve betonarme olmak üzere iki farklı şekilde oluşturulmuştur. TBDY Türkiye Bina Deprem Yönetmeliği 2018e göre mevcut ve ek katlı yapısal modellerin performans analizleri yapılarak, mevcut yapının deprem performansındaki değişim çelik ve betonarme ek katlı durumlar için karşılaştırmalı olarak irdelenmiştir. Yapısal modellere ait yapısal periyotlar, kat ötelemeleri, itme eğrileri, plastik mafsal oluşumları ve olası hasar mertebeleri kıyaslanarak mevcut yapı için performans ve uygunluk değerlendirmesi yapılmıştır. Yapının taşıma gücü dikkate alındığında her iki ek kat için güçlendirilmesi gereken eleman sayıları nispeten aynı olmaktadır. Diğer yandan, yapıda çelik ek kat imalatının plastik mafsal oluşumlarını 15.22 ye kadar, kat ötelemelerini ise 37.8e kadar azalttığı elde edilmiştir.
