This research investigates prefabricated light-gauge steel and concrete panels using
reliable and commercially viable shear connectors. An analytical and experimental
investigation was undertaken to study the flexural behaviour of light-gauge steel and
concrete composite panels under uniform pressure. Normalweight and lightweight
concrete panels were fabricated by embedding 16-gauge 41 mm x 203 mm steel channel
sections (running parallel to each other) to a depth of 38 mm into a 64 mm thick
concrete slab. Push-out tests were also conducted to evaluate the efficiency of three
types of shear connection mechanism; natural surface bonding, predrilled holes, and
punched holes. Only two types of shear connectors (predrilled holes and punched holes)
were used in the full-scale panel specimens.
Results show that the predrilled holes and punched holes provide full shear transfer
between the steel and concrete. The ultimate load carrying capacity of the lightweight
concrete panels exhibited similar behaviour to the normalweight concrete panels. All the
panels exhibited good load carrying capacity and ductility, and satisfied the
serviceability limit state of deflection. Thus, the proposed panels present a potential for
a commercially viable composite floor system for building construction utilizing a
maximum span of 2330 mm.
