• 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 ...

    • 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 ...

    • 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 ...

    • On the cooling potential of elastocaloric devices for building ventilation 

      Ulpiani, Giulia; Saliari, Maria; Bruederlin, Florian; Kohl, Manfred; Ranzi, Gianluca; Santamouris, Mat
      Published 2021
      Refrigerants in vapor-compression systems have a global warming potential thousands of times that of carbon dioxide, yet their spread on the market is unrivalled. Elastocaloric systems, based on solid state cooling, feature ...

    • Upscaling of SMA film-based elastocaloric cooling 

      Ulpiani, Giulia; Bruederlin, Florian; Weidemann, Raphael; Ranzi, Gianluca; Santamouris, Mat; Kohl, Manfred
      Published 2020
      A new concept of upscaling a shape memory alloy (SMA) film based elastocaloric cooling device is presented by arranging SMA films in parallel to increase the specific cooling capacity at low actuation force, while maintaining ...
