Abstract
AbstractRelatively little research has been reported on the time-dependent in-service behavior of composite concrete slabs with profiled steel decking as permanent formwork, and little guidance is available for calculating long-term deflections. The drying-shrinkage profile through the thickness of a composite slab is greatly affected by the impermeable steel deck at the slab soffit, and this has only recently been quantified. Based on an existing analytical model developed by the authors to calculate the time-dependent deflection of composite slabs, a simplified procedure, suitable for use in structural design, is proposed for calculating the time-dependent deflection of composite concrete slabs with steel decking as permanent formwork that takes into account the time-dependent effects of creep and shrinkage. The method is illustrated by three examples and the results are compared with the experimental data.
