Prequalifying Criteria for Hollow Structural Steel [HSS] Truss Connections

Mary, S. Arul / Sindhia, T. Rama

This paper presents prequalifying criteria for hollow structural steel [HSS] truss connections. The criteria were derived based on the parametric study on T, Y, X, N and K type hollow structural steel truss connections. The parametric study was undertaken with reference to the recommendation of CIDECT design guide-3. The more influencing geometric parameters taken in this study were the ratio of brace width to chord width (β parameter), ratio of brace thickness to chord thickness (τ parameter), chord and brace slenderness values, chord and brace aspect ratios. An experimental investigation on welded T and X type truss connections was conducted to validate the prequalifying criteria which were obtained through the parametric study on these connections. The most influencing geometric parameter found in this experimental validation was the ratio of brace width to chord width. The prime objective of this prequalifying criteria is that it qualifies the HSS truss connection such that at its ultimate it governs the chord face plastification connection failure.
