•The behaviour of UHPC/NC hybrid slab is investigated.•A validated FE model is used to study a wide range of parameters.•A design model is developed to predict the punching capacity of hybrid slabs. Flat slabs are commonly used in the construction of multi-storey buildings due to their ease of place...
