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.
Stainless steel built-up I-profile are frequently designed with webs significantly more slender than their flanges and greater material strength in the flanges in case of hybrid sections. Given the fundamental load case of pure compression or bending, the compressed flange can develop significant postlocal-buckling...

As a lightweight load‐bearing member for aerospace truss structures, thin‐walled metal tubes require improved buckling resistance without additional mass. To this end, this paper innovatively designs a thin‐walled metal inflatable tube structure. The axial compressive behavior of the proposed tube and the influence of...

The swift advancement of modern construction has established cold-formed steel (CFS) as a prominent structural option owing to its high strength-to-weight ratio and lightweight properties. However, CFS in open sections such as channel and zee sections is heavily restricted by susceptibility to premature instabilities s...

To study the axial compression performance of steel tube-confined concrete, nine short column specimens were designed for axial compression testing. The parameters are the diameter-to-thickness ratio of steel tubes and the contact treatment method at the steel-concrete interface. The failure mode, load-displacement cur...

Sixteen reinforced concrete beams were tested under symmetric concentrated loading to investigate the mechanical behavior of beams designed using the compressive force path (CFP) method, in comparison with specimens designed according to the Chinese Code for Design of Concrete Structures (GB 50010-2010). The test varia...
The study presents the results of model experimental investigations and nonlinear numerical analyses of thin-walled, two-segment box structures with various configurations of integral corrugated stiffeners. The models for experimental testing were fabricated using additive manufacturing techniques. Five variants of the...
