The Efficiency of Utilisation of High-strength Steel in Tubular Profiles
Abstract
The use of high-strength steel (HSS) is a current trend of the construction industry. Tubular profiles are widely used in various structural applications because of their high stiffness-to-weight ratio, exceptional resistance to torsion, and aesthetic appearance. However, the increase of the strength for the same elastic modulus of the material and geometry of tubular profiles is often not proportional to the rise of the load-bearing capacity of the structural element. The obtained experimental results support the above inference. The study was based on the flexural test results of two groups of HSS and normal-strength steel (NSS) tubular specimens with a 100 × 100 × 4 mm (height × width × thickness) cross-section. Numerical (finite element) simulation results demonstrated that the shape of the cross-section influenced the efficiency of utilisation of HSS. The relationship between the relative increase of the load-bearing capacity of the beam specimen and the corresponding change of the steel strength determined the utilisation efficiency. ; This article belongs to the Special Issue Advanced Composites: From Materials Characterization to Structural Application ; The European Social Fund provided a financial support for this research within the framework of the project “Development of Competences of Scientists, other Researchers and Students through Practical Research Activities” (project no. 09.3.3-LMT-K-712).
