Abstract

A steel joist for use in a composite steel and concrete construction consists of a web (17), a bottom chord (16) and a double top chord (18) construction consisting of two elongated substantially identical members (21) each of S or Z cross-section and being connected to or integral with the web (17). The members (21) are positioned in mirror relation tone another to provide symmetry about a vertical axis, and in use are embedded in a concrete slab, with the web (17) and bottom chord (16) not being embedded in the concrete.
