Abstract

This study aims to experimentally investigate the buckling behavior and load-bearing capacities of cold-formed steel (CFS) omega-section columns under axial load. Within the scope of the research, 11 omega column specimens with thicknesses ranging from 1.75 mm to 3 mm were integrated with corrugated silo wall sheets of various thicknesses and subjected to axial compression tests. The experiments were designed to analyze the effects of lateral restraint conditions and column thickness on load-bearing capacity, post-elastic behavior, and failure modes. The findings fill a significant gap in literature by demonstrating the interactive performance of omega sections with secondary elements like silo walls. This study provides critical data for the design of these thin-walled members in modern construction applications.

Özet

Bu çalışma, soğukta şekil verilmiş çelik (CFS) omega kesitli kolonların eksenel yük altındaki burkulma davranışlarını ve taşıma kapasitelerini deneysel olarak incelemeyi amaçlamaktadır. Araştırma kapsamında, 1.75 mm ile 3 mm arasında değişen et kalınlıklarına sahip 11 adet omega kolon numunesi, farklı kalınlıktaki dalgalı silo duvarı levhalarıyla birleştirilerek eksenel basınç testlerine tabi tutulmuştur. Deneyler, yanal destek koşullarının ve kolon et kalınlığının yük taşıma kapasitesi, elastik ötesi davranış ve göçme modları üzerindeki etkilerini analiz etmek üzere kurgulanmıştır. Elde edilen bulgular, omega kesitlerin silo duvarı gibi ikincil elemanlarla etkileşimli çalışma performansını ortaya koyarak literatürdeki önemli bir boşluğu doldurmaktadır. Çalışma, ince cidarlı bu elemanların modern inşaat uygulamalarındaki tasarımı için kritik veriler sunmaktadır.
