Overview

Experimental and numerical assessment of HSS welded H-sections' performance reveals design standard implications.

Key Points

  • HSS welded H-section columns exhibit varying resistance predictions under major-axis combined loading with temperature considerations.
  • Experimental tests at 600°C and parametric FEM analysis provide insights into design standards’ applicability for HSS columns.
  • The study shows that European and American standards predict conservative flexural buckling resistances, confirming design curve reliability.
  • Chinese design specifications exhibit a conservative approach, yet DSM predictions appear overly optimistic in comparison.
