This work presents an experimental and theoretical study on the punching shear behavior of Lightweight Concrete Slabs. obtained using Expanded polystyrene (EPS) beads as partial coarse aggregate’s replacement, without adding supplementary bonding additives, to reduce concrete density from 2400 1800 kg/m 3 . The EPS content, strength column aspect ratio were test parameters. Five groups prepared...

Abstract In flat-slab frames, which are typically designed as secondary seismic structures, the shear failure of slab around column (punching failure) is governing mode limits deformation capacity and can potentially lead to a progressive collapse structure. Existing rules predict flat frames resist imposed lateral displacements without losing capability bear gravity loads have been derived emp...

Punching shear-reinforced flat slabs can fail in three modes: (1) inside the zone, (2) outside or (3) at maximum punching shear capacity. By using theory of structural systems reliability, this study investigates how these failure modes combined affect safety level reinforced concrete with reinforcement, and ultimately, variation partial factors. Based on DIN EN 1992-1-1 together German Nationa...
