Abstract:

 In steel structures, it may be necessary to provide large openings in the beam webs, especially for plumbing transitions. However, such voids can significantly reduce the shear and moment carrying capacity of the beams and adversely affect the structural performance. Although the effects of web openings have been extensively studied in the literature, systematic and comprehensive approaches to mitigate these effects are limited. In this study, the effectiveness of different strengthening strategies to minimize the structural performance losses of an 8 m long steel beam with IPE600 cross-section and 400x700 mm plumbing openings in its web is investigated. Linear buckling and nonlinear analyses were performed on the simply supported beam modeled in accordance with Eurocode 3. The results were evaluated in terms of failure loads, moment capacities and deformation parameters. Based on these analyses, the strengthening arrangement that provides the closest results to the bearing capacity of the reference model was determined. The findings of the study indicate that structural performance can be improved by strengthening steel beams with web openings and that such optimal design approaches can be more widely used in the design process of steel structures.

 Çelik yapılarda, kiriş gövdelerine büyük boşluklar açılması, özellikle tesisat geçişleri nedeniyle gerekli olabilmektedir. Ancak, bu tür boşluklar kirişlerin kesme ve moment taşıma kapasitesini önemli ölçüde azaltarak yapısal performansı olumsuz etkileyebilir. Literatürde gövde boşluklarının etkileri geniş çapta incelenmiş olsa da bu etkileri azaltmaya yönelik sistematik ve kapsamlı yaklaşımlar sınırlıdır. Bu çalışmada, gövdesinde 400x700 mm boyutunda tesisat boşluğu açılmış IPE600 enkesitli 8 m uzunluğunda bir çelik kirişin yapısal performans kayıplarını en aza indirmek için farklı güçlendirme stratejilerinin etkinliği araştırılmıştır. Eurocode 3e uygun şekilde modellenen basit mesnetli kiriş üzerinde lineer burkulma ve doğrusal olmayan analizler gerçekleştirilmiştir. Sonuçlar, göçme yükleri, moment kapasiteleri ve şekil değiştirme parametreleri açısından değerlendirilmiştir. Bu analizler ışığında, referans modelin taşıma kapasitesine en yakın sonuçları sağlayan güçlendirme düzenlemesi belirlenmiştir. Çalışmanın bulguları, gövde boşluklu çelik kirişlerin güçlendirilmesi yoluyla yapısal performansın artırılabileceğini ve bu tür optimum tasarım yaklaşımlarının çelik yapıların tasarım süreçlerinde daha yaygın bir şekilde kullanılabileceğini göstermektedir.
