Performance of reinforced concrete flat slab strengthened with CFRP for punching shear
Case Studies in Construction Materials, 2023 Existing reinforced concrete (RC) slabs need punching shear reinforcement due to design defects, structural damage, increased loading, corroded reinforcement bars, and change in the use or function of the buildings.

Enhancement of the punching shear verification of slabs with openings
Structural Concrete, 2022 Openings in flat slabs near to columns are often needed to supply the building with utilities. The presence of these openings can lead to a decrease of the punching resistance which is related to (i) the reduction of the control perimeter, (ii) the ...

The calibration of NLFE model for the assessment of the maximum punching capacity of flat slabs [PDF]
MATEC Web of Conferences, 2023 The requirements on structural engineers to design more subtle flat slabs are still increasing and therefore they must often design a large amount of reinforcement against punching. The maximum amount of transverse reinforcement is limited by the maximum

Punching Shear Strength of Reinforced Concrete Flat Plates with Openings
Jurnal Engineering, 2023 Test results of six half-scale reinforced concrete flat plates connections with an opening in the vicinity of the column are reported. The test specimens represent a portion of a slab bounded by the lines of contraflexure around the column.
