Experimental study on flexure rigidity of composite slabs with closed profiled steel sheeting

Experiments of 8 composite slabs with closed profiled steel sheeting as well as 6 composite slabs with light weight concrete and closed profiled steel sheeting were conducted.Two key factors of varied forms of studs on the end of the composite slabs and different shear span ratio were considered.Based on the experimental results,three calculation methods of rigidity of the composite were studied,and the mid-spandeflections of the compositeslab, specimens calculated by these three calculation methods were compared with the test results.Finally the rigidity calculation method on the basis of reinforced concrete flexure members was recommended,which was proved be more accarate on calculating the composite slabs with closed profiled steel sheeting than the equivalent section methods.
