The local or global progressive collapse of reinforced concrete (RC) flat slab structures may occur due to the failure of load-bearing columns under accidental loading; such as explosion and impact. In order to investigate the effect of slab reinforcement details on the progressive collapse performance of RC flat slab structures; two one-third scale RC flat slab substructure models are constructed and tested under monotonic static load in the scenario of loss of a corner column. Experimental results show that (1) continuous top slab reinforcement can effectively reduce the width of cracks on the slab; (2) as compared with the specimen with discontinuous top slab reinforcement; the yield load; first peak load and ultimate bearing capacity of the substructure with continuous top slab reinforcement increase respectively by 38.4%; 31.8%; and; 7.5%; and the progressive collapse resistance under dynamic load is significantly improved as well; and (3) the tensile membrane action in the slabs contributes significantly to the progressive collapse resistance after the working mechanism of yield lines fails. ©; 2014; South China University of Technology.
