Punching Shear in Concrete Slabs

Concrete flat slabs are a popular form of flooring system used for a wide range of buildings such as offices, warehouses and carparks, since they provide large, uninterrupted floor areas with no downstand beams within a minimum construction depth. In flat slab construction without beams, two problems have to be avoided: (1) large deflections at service loads and (2) punching shear failures at column-slab connections. This note is concerned with the second of these problems. Deflections in flat slabs will be the subject of a subsequent technical note. P.S. Chana
