Improvement of the Method for Fixing a Punch in the Punch Holder [PDF]
Applied Sciences, 2021 The punching process allows large quantities of parts to be produced at very low cost. This paper studies how the technique used for fixing a punch can be improved in order to increase productivity before punch fracture, which results in large numbers of parts failing to be produced, thus creating a significant shortfall.

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

Strength of cast-in-place slabs for rectangular cross-section columns punching [PDF]
E3S Web of Conferences, 2021 Flat slabs in contemporary buildings are most commonly supported by rectangular cross-section columns. Research of slabs supported by rectangular cross-section columns for punching is rather narrow.

Progressive Collapse Analysis Of Flat Slab Buildings With Post-Punching Effect [PDF]
مهندسی عمران شریف, 2021 The reinforced concrete flat slab is one of the types of floor systems used to construct residential, office and parking buildings. Because of the direct transfer of floor loads to columns, flat slabs are susceptible to punching failure in slab-column ...

Punching Shear Strength of Voided Slab: Literature Review and Evaluation of Design Codes
Wasit Journal of Engineering Sciences, 2022 Despite of the economic advantages provided by the voided slabs, their design against punching shear failure, as suggested by the current building codes, are based on the equations derived from tests on flat slabs.
