Effect of different parameters on lateral-torsional buckling behavior of I-girders with circular corrugated webs

Journal of Engineering and Applied Science, 2022
I-girders with circular corrugated webs are considered as a new fabrication technology. The corrugation of the web considerably increases the stiffness of the cross-section to resist shear forces and also increases the out-of-plane stiffness.

Shear behavior of stainless steel girders with corrugated webs

Journal of Constructional Steel Research, 2023
This paper reports experimental and finite element investigations conducted to assess the shear strength of corrugated web girders in stainless steel. The steel under consideration is LDX 2101. Four trapezoidal corrugated web girders were tested under shear. All tested girders reached the shear yield strength followed by strain hardening.
