Abstract

Reliability Assessment of Existing Equations Predicting the Shear Strength of Reinforced Concrete Beams without Stirrups Codes keep the probability of shear failure low in order to prevent a reinforced concrete member from reaching its ultimate strength through shear failure, which is sudden and brittle. Numerous equations for predicting the cracking shear strength of a reinforced concrete beam without stirrups have been proposed in the previous studies. In this study, performance functions related to the equations given by four codes and seven researches are developed considering beams with various geometrical and material properties. The reliability of these equations is assessed based on the performance functions by using second-moment approach. According to the failure probabilities based on different distributions, it is observed that the equation given by EN92 is the most reliable one

Özet

Yönetmelikler, betonarme elemanların yük taşıma kapasitelerine ani ve gevrek olan kesme kırılması ile ulaşmasını engellemek için kesme kırılması oluşması olasılığını azaltmıştır. Günümüze kadar yapılan çalışmalarda, enine donatısız betonarme kirişlerin eğik çatlama kesme mukavemetlerinin tahmini için çok sayıda bağıntı önerilmiştir. Bu çalışmada, farklı geometri ve malzeme özelliklerine sahip kiriş toplumu gözönüne alınarak dört farklı yönetmelik ve yedi farklı araştırmada önerilen bağıntılara ilişkin performans fonksiyonları oluşturulmuştur. Bu performans fonksiyonları esas alınarak enine donatısız betonarme kiriş kesme mukavemeti bağıntılarının güvenilirliği ikinci-moment yaklaşımı kullanılarak değerlendirilmiştir. Değerlendirme sonucu, farklı dağılımlar için belirlenen göçme olasılıklarına göre güvenilirliği en yüksek olan bağıntının EN92 olduğu görülmüştür
