BUCKLING CAPACITY OF COLD-FORMED STEEL SECTIONS WITH WEB HOLES USING DIFFERENT APPROACHES

Abstract

This study examines the buckling behavior of cold-formed steel sections with web holes under bending. Perforated sections are widely used in structural applications to accommodate openings for electrical, plumbing, and ventilation systems. However, these holes significantly affect the section's mechanical properties and buckling behavior. Elastic buckling analyses were conducted for both perforated and non-perforated sections using CUFSM, considering variables such as hole height, hole length, and section height. Additionally, the effectiveness of different approaches in predicting local and distortional buckling capacities was compared. The results indicate that hole height and hole length significantly influence buckling capacity. In particular, when the hole length exceeds 80 mm, local buckling capacity increases, while distortional buckling capacity decreases. Furthermore, comparison of different methods revealed that the approach developed by Moen and Scahfer produced results similar to standart approaches, whereas some other methods tended to overestimate the local buckling capacity and underestimate the distortional buckling capacity.

Öz

Bu çalışma, gövde delikli soğukta şekil verilmiş çelik kesitlerin eğilme etkisi altındaki burkulma davranışını incelemektedir. Delikli kesitler, elektrik, su ve havalandırma sistemleri için gerekli boşlukları sağlamak amacıyla yapısal uygulamalarda yaygın olarak kullanılmaktadır. Ancak bu delikler, kesitin mekanik özelliklerini ve burkulma davranışını önemli ölçüde etkilemektedir. Bu kapsamda, delik yüksekliği, delik uzunluğu ve kesit yüksekliği gibi değişkenler dikkate alınarak, CUFSM programı kullanılarak deliksiz ve delikli kesitler için elastik burkulma analizleri gerçekleştirilmiştir. Ayrıca, farklı yaklaşımların lokal ve distorsiyonel burkulma kapasitelerini tahmin etmedeki etkinliği karşılaştırılmıştır. Elde edilen sonuçlar, delik yüksekliği ve delik uzunluğunun burkulma kapasitesi üzerinde önemli bir etkisi olduğunu göstermektedir. Özellikle delik uzunluğunun 80 mm’yi aşması durumunda, lokal burkulma kapasitesinin arttığı, ancak distorsiyonel burkulma kapasitesinin azaldığı belirlenmiştir. Ayrıca, farklı yöntemlerin karşılaştırılması sonucunda, Moen ve Schafer tarafından geliştirilen yaklaşımının standart hesaplamalarla benzer sonuçlar verdiği, buna karşın bazı diğer yöntemlerin lokal burkulma kapasitesini yüksek, distorsiyonel burkulma kapasitesini ise düşük tahmin ettiği tespit edilmiştir.
