Hollow-core concrete columns are more desirable in the construction of tall structures, bridge piers and piles, and electric poles because the hollow-core reduces the self-weight and leads to a structure or a structural component with a high strength-to-weight ratio [2,5,7]. Generally, hollow-core concrete columns are reinforced with steel

Due to the under-reinforced nature of hollow-core slabs, concrete crushing is unlikely to control; this is confirmed in this study. Similarly, prestressing wire rupture is unlikely as these wires have relatively high rupture strains and are prone to slip (due to lack of deformations) following concrete cracking.

low-core slabs because the location and size of the openings plays an important role in the capacity and failure mode of the hollow-core slabs. H ollow-core slabs are precast, prestressed concrete elements used as slab components in buildings. It is common to have openings in the slabs for various structural reasons, such as provision of columns or

The influence of a hollow core in a precast concrete slab reinforced with GFRP bars was evaluated by comparing the behaviour of slabs S1 and S2. Results indicated that the structural behaviour of solid and hollow core slabs was similar as both slabs exhibited same cracking propagation and failed by the concrete crushing and buckling of bars
