Abstract
Türkiye Erzurum İli Şenkaya İlçesinde yer alan Yünören Köprüsünün, Türkiye’de yaşanmış büyük depremler etkisinde performansının belirlenmesi ve köprünün güçlendirilmesi için mevcut yöntemler kullanılarak çalışma yapılmıştır. Çalışmada, SAP2000 paket programı ile köprü üç boyutlu olarak modellenmiş ve yine analiz sonuçları bu programdan alınmıştır. Analiz sonuçlarına göre, köprü ayaklarının ileri hasar seviyesinde ve ana taşıyıcı kirişlerinin ise göçmenin önlenmesi hasar seviyesinde olduğu gözlemlenmiştir. Yapıdaki hasarları en aza indirgemek için, yapıda doğrusal olmayan yer değiştirmelerin yoğun olduğu kirişlerin dönme merkezine sismik sönüm cihazı yerleştirilmiştir. Ayrıca, ek güçlendirme yöntemi olarak kirişlerin deprem esnasında düzlem dışı burkulmasını önlemek için, kirişler yanal stabilite bağlantılarıyla desteklenmiştir. Elde edilen yapının üç farklı durumu, analiz edilerek sonuçlar karşılaştırılmıştır. Yanal stabilite bağlantılarıyla oluşan yapının sünek davranış gösterdiği ve sismik sönüm cihazı yerleştirilen tasarımda da yapının benzer şekilde belirgin hasar düzeyinde kaldığı gözlemlenmiştir. Yapının oluşabilecek deprem esnasında göçmeden ayakta durabilmesi için tasarımı yapılan şekliyle güçlendirilmesi gerektiği kanısına varılmıştır.

Abstract
This sentence needs rephrasing: Turkey Erzurum Province, located in the district of Şenkaya Yunoren Bridge, experienced major earthquakes in Turkey have been studied using the present method for determining the effect of performance and strengthening the bridge. In the study, the bridge was modeled in three dimensions with the SAP2000 package program, and the analysis results were obtained from this program. According to the analysis results, it was observed that the building columns were at the advanced damage level and the main carrier beams were at the damage level to prevent collapse. In order to minimize the damages in the structure, a seismic damping device was placed in the center of rotation of the beams where non-linear displacements are intense. Another strengthening method is to support the beams with lateral stability connections to prevent out-of-plane buckling of beams during earthquakes. Three different situations of the obtained structure were analyzed, and the results were compared. It was observed that the structure formed by the support of the beam with lateral stability joints displayed a ductile behavior and remained at an obvious damage level and the structure in which the seismic damping device was installed remained at the level of obvious damage. It has been concluded that the building should be strengthened in order to stand without collapse during an earthquake.
