The Behaviour of Half-Slabs and Hollow-Core Slab in Four-Edge Supported Conditions

In this study, qualitative tests were carried out to compare the behaviour of selected slabs exposed to short- and long-term loading. Full-scale models of the half-slab and hollow-core slab with dimensions of 6.30 m × 6.30 m, built of four different precast panels, were tested. The first two were se...
