Research Description
Flat-slab systems are popular because of their adaptability. Connecting to public services like gas or deflation may require
openings. Most designers cannot choose where these openings should be relative to the supporting column. Openings
and flat slabs, especially those with edge columns, create a concrete-reinforcing steel discontinuity that punches. Concrete
slab capacity depends on its cross-section's punching shear resistance. A 1500×1000×120 mm specimen was studied in
an experiment. This specimen has no openings or shear studs. The specimen's maximum load, deflection, energy
absorption, and stiffness were determined experimentally. Using ANSYS V.21, to compare the experimental results with
numerical results. Also, using ANSYS V.21 to study many finite element models on larger slab dimensions
3000*3000*150 mm. The shear stud scheme in a flat slab with openings, the opening size relative to the column face and
column corner, the opening locations close to them, the ideal number of studs in one row, the ideal distance between
rows, the ideal arrangements of shear studs, and the number of rows were studied. The experimental and numerical
findings were compared using ANSYS V.21. Experimental and ANSYS V.21 results were close. ANSYS V.21
demonstrated that flat slab openings at the column corner had better ultimate load capacity than those at the column face,
while increasing opening dimensions beyond the column dimension decreased punching shear capacity. Additionally,
the best location for shear studs in a box layout is three of them spaced at a distance of ts mm. Also, The shear resistance
rises with increasing row numbers
