A square column 379 mm x 379 mm rests on a square footing. The column supports a dead load of 1,105 kN and a live load of 739 kN. The soil bearing capacity is 300.82 kPa. The base of the footing is 1.84 m below the ground. Assume unit weight of concrete of 24 kN/m3 and unit weight of soil of 17.63 kN/m³. The footing has a thickness of 591 mm and the centroid of the main bars is 100 mm from the bottom of the footing. Calculate the nominal punching shear stress in MPa. Note: Present the width (B) in multiples of 100 mm.

Transcribed Image Text:A square column 379 mm x 379 mm
rests on a square footing. The
column supports a dead load of
1,105 kN and a live load of 739 kN.
The soil bearing capacity is 300.82
kPa. The base of the footing is 1.84
m below the ground. Assume unit
weight of concrete of 24 kN/m3 and
unit weight of soil of 17.63 kN/m³.
The footing has a thickness of 591
mm and the centroid of the main
bars is 100 mm from the bottom of
the footing.
Calculate the nominal punching
shear stress in MPa.
Note: Present the width (B) in
multiples of 100 mm.
