Abstract:
An experimental investigation was conducted at the University of Auckland to quantify the performance of shear studs embedded in composite ribbed slabs, formed by casting lightweight polystyrene concrete onto profiled steel decking. In total, 18 tests were conducted using a new type of push-off test rig, with test units composed of either lightweight polystyrene concrete or normal weight con- crete (to facilitate performance comparison). This paper reports and discusses the main results of those 18 tests. Results indicated that in most cases designs utilizing lightweight polystyrene concrete had considerable ductility and shear capacity. Recommended design provisions based on the experimental data are presented.
