Evaluation of punching shear strength of voided slabs considering the effect of the ratio b0/d
TLDR
In this article, the authors evaluated the punching shear strength of voided slabs according to the arrangement of voids through experimental tests and numerical simulations, and determined that the void-based reduction of the cross-sectional area at the control perimeter and the ratio of the length of the controlling perimeter to the effective depth of the slab were the factors that influenced the punching-shear strength.About:

Improving punching behavior of interior voided slab-column connections using steel sheets
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.

Structural behavior of reinforced concrete one-way slabs voided by polystyrene balls
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).

R. Sagadevan,B. N. Rao +1 more
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.

Quasi-static analysis of biaxial voided slabs with openings
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.

Study on shear behavior and capacity of biaxial ellipsoidal voided slabs
TL;DR: In this paper, a method was proposed to predict the ratio of shear capacity of biaxial-voided slabs to solid slabs with an adequate precision, and the effect of vertical rods of steel cages on the shear behavior was investigated.

The theoretical basis of a method to determine the fracture energy GF of concrete
TL;DR: In this article, the significance of fracture energy in the strength of concrete structures is discussed and it is demonstrated that GF in some cases, for example for shear failure of beams and slabs without shear reinforcement, is a material property which may be as important as normal strength properties.

Punching shear strength of steel fibre reinforced concrete slabs
TL;DR: In this paper, a mechanical model for predicting the punching strength and behaviour of concrete slabs reinforced with steel fibres as well as conventional reinforcement is presented. And the proposed model is validated against a wide number of available experimental data and its accuracy is verified.

Punching behavior of biaxial hollow slabs
TL;DR: In this paper, the influence of the cavities on the punching behavior of a hollow slab with plastic balls as hollow bodies was investigated and necessary modifications of existing design recommendations according to German design code DIN 1045 were developed.

Shear Strength of Continuous Plates
TL;DR: In this paper, the punching shear test of 15 reinforced concrete specimens of a new type of test specimen that simulates continuous two-way construction is reported, and the results of these tests are that: (1) Circular columns permit development of higher shear strength than square columns of equal periphery; (2) increasing moment reinforcing results in a slight increase; (3) none of the empirical strength equations extant are reliable; and (4) conventional footing type test specimens are adequate for parameter studies.
