TL;DR: In this paper, the applicability of conventional methods for solid slabs in the design standards, such as ACI 318 (2014), EN 1992-1-1 (2004) and IS 456 (2000), to predict the punching shear capacity of the voided slab is examined.

TL;DR: In this article, a method for improving the punching shear strength and behavior of voided slabs by employing steel sheets was presented, and the results revealed that significant losses were recorded in the strength, stiffness, ductility and energy absorption of the voided slab without sheets compared with the reference one.

TL;DR: In this article, the effect of void size on the structural behavior of one-way slabs was evaluated using self-compacting concrete and polystyrene balls with different sizes (60mm, 70mm, and 90mm).

TL;DR: In this paper, a new punching shear strength formula for either FRP or steel reinforced two-way concrete slabs based on deterministic and probabilistic methods was proposed.

TL;DR: In this paper, the authors compared the bubble slabs experimentally with solid slabs under the influence of limited repeated four-point loads, and the results showed that the balls' presence made slabs failed abruptly due to shear mode regardless of the a/d.

TL;DR: In this paper, 3D nonlinear finite element analyses (FEA) were conducted using the ABAQUS program to investigate the openings' influences on voided slabs' structural behaviors.
