Abstract (2. Language): 
Design of the distance of bolts to each other and design of the distance of bolts to the edge of connection plates are made based on minimum and maximum boundary values proposed by structural codes. In this study, reliabilities of those distances were investigated. For this purpose, loading types, bolt types and plate thicknesses were taken as variable parameters. Monte Carlo Simulation (MCS) method was used in the reliability computations performed for all combination of those parameters. At the end of study, all reliability index values for all those distances were presented in graphics and tables. Results obtained from this study compared with the values proposed by some structural codes and finally some evaluations were made about those comparisons. Finally, It was emphasized in the end of study that, it would be incorrect of the usage of the same bolt distances in the both traditional designs and the higher reliability level designs.
Abstract (Original Language): 
Cıvatalı çelik yapı elemanı birleşimlerinde, cıvatalar arası uzaklıkların ve cıvataların çelik levha kenarına uzaklıklarının tasarımı yönetmeliklerde belirtilen minimum ve maksimum sınırlar temel alınarak yapılmaktadır. Bu çalışmada cıvatalı birleşimlerdeki cıvatalar arası ve cıvataların birleşim levhası kenarlarına olan mesafelerinin güvenilirlikleri araştırılmıştır. Bu amaçla yükleme türü, cıvata türü, birleşim levhası kalınlığı, değişken olarak alınmıştır. Bu parametrelerin tüm kombinasyonları için gerçekleştirilen güvenilirlik analizlerinde Monte Carlo Simülasyon (MCS) yöntemi kullanılmıştır. Çalışmanın sonucunda elde edilen güvenilirlik indeksi değerleri grafikler ve tablolar halinde sunularak elde edilen sonuçlar ile bazı yönetmeliklerde önerilen değer aralıkları karşılaştırılarak elde edilen bulgular üzerinde değerlendirmeler yapılmıştır. Sonuç olarak geleneksel ve güvenilirlik düzeyi daha yüksek tasarımlar için aynı cıvata aralıklarının kullanımının hatalı olacağı vurgulanmıştır.
