Description

A ten-metre span, simply-supported, overlap-jointed, rectangular hollow section (RHS) Warren truss was tested elastically by applying a single quasi-static point load to various chord panel points to obtain experimental axial force, bending moment, and truss deflection patterns. A total of 53 axial forces and bending moments were measured in the chord and web members during two tests, and deflections at panel points along the bottom chord were measured during a broader series of nine tests. The theoretical behaviour given by practical frame analysis models, consisting of: (i) all joints pinned and concentric; (ii) all joints rigid and concentric; (iii) pin-ended webs connected eccentrically to continuous chords; and (iv) rigid-ended webs connected eccentrically to continuous chords, has been compared to the experimental results. Recommendations are thus made for the analysis of welded RHS trusses with overlapped K-connections.
