• Fracture Investigation of Welded Cruciform Connections 

      Liu, Xiaofan; Yan, Shen; Rasmussen, Kim JR; Deierlein, Gregory G
      Published 2023
      As one of the main failure modes of steel structures, fracture in welded connections has widely been discussed based on experimental investigations and numerical simulations. However, the mechanical properties of the weld ...

    • Stiffness Reduction of Cold-Formed Steel Structures Subject to Sectional Buckling and Yielding 

      Rasmussen, Kim JR
      Published 2022
      The paper develops a stiffness reduction factor to be used in geometric nonlinear beam-element type elastic analysis of cold-formed steel structures. The factor accounts for the reduction in flexural and warping torsion ...

    • Strengths and Fracture Strains of Weld and HAZ in Welded Connections 

      Liu, Xiaofan; Yan, Shen; Rasmussen, Kim JR; Deierlein, Gregory G
      Published 2023
      This paper investigates the strengths and fracture strains of weld and heat affected zone (HAZ) in welded connections for both the longitudinal and transverse directions and compares them to those of the base metal. A ...
