Flat slabs are widely used due to their advantages. However, punching collapse is a
situation that should not be ignored during the design as a risk in this type of slab. The …

The arrangement of openings adjacent or near to slab-column connections is very common
practice in flat slab design due to a number of advantages for technical installations. Such …

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 …

Experimental evidence have proved that punching shear capacity of flat slabs deteriorate
with the presence of openings located within the critical perimeter around columns. It is …

The impact of openings and moment transfer on punching shear resistance was investigated
by conducting tests on nine interior slab-column connections measuring 2,400 mm square …

Flat slabs have been widely used to allow the larger interior areas to be created in
architectural plans, reduce the height of the building by allowing more story heights, and …

The present study aims to parameterize the numerical models of flat slabs based on five
experimental prototypes developed previously. The analyzed slabs had dimensions of 1800 …

Self-curing concrete is one of the most notable enhancements in modern concrete
technology. The study presents experimental and numerical investigations conducted to …

Reinforced concrete flat slab projects usually require openings close to the columns for
electrical and hydraulic installations. Since such openings reduce the punching shear of …

Background Dimensions of the reference concrete slab are 1950x1950x100 mm subjected
to drop-weight impact loading. Objective a comprehensive parametric study was performed …
