The flexural behavior of 2 composite trusses with a span of 11.5 m was studied. The truss configuration consisted of hollow structural section chords with double angle web members welded on either side. The flexural tests showed that ductile behavior up to failure can be obtained without failure of the web members, provided that the design is based on the ultimate tensile strength of the bottom chord, and the web members and shear connection are designed for the concomitant forces. Observations of the maximum strain and the maximum moments are discussed. The failure mode of the first composite truss demonstrated the need for additional rules for establishing the length of stud shear connectors for use in slabs on ribbed decks, as has been incorporated in S16.1-M89. A design procedure for double angle web members was developed, based on the test results.
