Cutting security of strip footing not always provided

This message is created at the beginning of the report by giving the name of the element and its solid.

For example,

TK1, Ground Floor Shear Safety not provided

In all elements:

And ≤ 0.22 fcd bw d

The cut-off insecurity is based on two conditions.

  1. Vr breaking capacity and if the design remains smaller than the cutting force. (And must be <Vr)

  2. And if the design exceeds the Vmax, which must be controlled from the shear force as per regulation

Possible Solutions:

  • For cases 1 and 2, the cross section dimensions of the named and solid element can be enlarged.

  • For case 2, it can increase the transverse (for stirrup selection) reinforcement diameters that can be used for the relevant element in the Reinforcement Selection dialog.

  • Concrete and reinforcement class can be increased for the 1st and 2nd case.



Ac = Column and curtain cross section area

fck = characteristic cylinder compressive strength of concrete

bw = Section width

d = Section height

fcd = Design compressive strength of concrete

Ve = Design shear force calculated under the effect of an earthquake with increased vertical loads
