Analysis of Rectangular Hollow Section Trusses

A database of 26 previous full-scale experiments on RHS trusses is supplemented by nine tests on a 10-metre-span, simply supported, RHS Warren truss, reported herein. Measured axial forces, bending moments and truss deflections are compared to four 2D, elastic, 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. On average, all four models predict sufficiently accurate axial force distributions and deflections under elastic loading. However, all four models under-predict bending moment magnitudes. Implications for RHS truss analysis according to the â detailed methodâ of CSA S16-14 are discussed, and recommendations for modelling are made.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
