Abstract
This experimental work aims to study the behaviour of reinforced concrete flat slabs, without shear reinforcement, under gravity and horizontal loading. The effect of gravity load ratio, drift amplitude and horizontal loading nature (cyclic or monotonie) were the studied variables, to ascertain its influence in load and drift capacity, as well as slab-column connection degradation. To accomplish this, four si milar flat slab specimens, measuring 4.15 × 1.85×0.15m3, were tested under different test protocols, using an innovative test setup whose boundary conditions better approximate laboratory specimens to reality. The obtained results show that cyclic horizontal loads are extremely detrimental to the slab-column connection. The observed drift capacity is not satisfactory, even under low gravity loads.
