Abstract: Light steel construction comprises cold formed steel sections of typically 1.2 to 3.2 mm thickness. Composite construction is well established using hot rolled steel sections, but this paper explores the applications of light steel construction acting compositely with in-situ concrete or heavy duty boarding materials.

A composite beam system is described which uses profiled strip or ‘top-hat’ shear connectors attached by pins to double C sections. A full-scale load test demonstrates its load resistance and stiffness for a 9m beam span.

A complete building system may be envisaged which uses C and Z sections acting as permanent formwork to in-situ concrete. Walls may be constructed from two skins of vertically orientated decking which possess high compression and shear resistance, as demonstrated by a series of load tests.

Flooring and walling materials can improve the stiffness of light steel floor joists and wall panels, and the results of various serviceability tests are presented which demonstrate the increase in stiffness that can be achieved. A full-scale test on a 2 storey building constructed using light steel framing shows that the masonry cladding can have an important effect on the shear resistance and stiffness of the building.
