The gross allowable soil pressure is 100 kPa and width of the wall is 200mm. Assume that the top of the footing is at the ground level. A) What should be the width (m) of the footing so that the allowable soil pressure will not be exceeded? (Dimensions in multiples of 50mm) B) Check the adequacy of the footing for Beam Shear considering 1m strip C) Calculate the required spacing reinforcements for diameter 16mm main bars and 10mm shrinkage and temperature bars.

The gross allowable soil pressure is 100 kPa and
width of the wall is 200mm. Assume that the top of
the footing is at the ground level.
A) What should be the width (m) of the footing so
that the allowable soil pressure will not be
exceeded? (Dimensions in multiples of 50mm)
B) Check the adequacy of the footing for Beam
Shear considering 1m strip
C) Calculate the required spacing reinforcements for
diameter 16mm main bars and 10mm shrinkage and
temperature bars.
