Steel-board composite floors

Work currently underway in Holland aDd the UK aims to increase the already considerable potential for light steel framing in buildings by developing rules for so-called "dry composites". This paper discusses both theoretical and experimental work to develop validated design mies for floor systems comprising cold formed joists and timber boarding. Preliminary results show that for practical board-to-joist connection details, a bending stiffness enhancement of around 30% can be expected
