Steel–Concrete–Steel sandwich slabs with lightweight core — Static performance

This paper investigates the static performance of Steel–Concrete–Steel (SCS) sandwich slabs which consist of an ultra-lightweight concrete core sandwiched between two steel plates. Special J-hook connectors have been developed to develop composite action between the concrete core and the two steel plates. The core is made of lightweight concrete of density less than 1450 kg/m3. Laboratory tests were carried out on eight SCS sandwich slabs under...
