Column cutting security is not provided
This message is created at the beginning of the report by giving the name of the element and its solid.
S8, Ground Floor Shear Security not provided
On the columns:
And it should be 0.85 Aw √ fck.
In all elements:
Vd ≤ should be 0.22 fcd bw d (TS 500).
And ≤ must be 0.22 fcd bw d (TS 500)
The cut-off insecurity is based on two conditions.
Vr breaking capacity and if the design remains smaller than the cutting force. (And must be <Vr)
And if the design exceeds the Vmax, which must be controlled from the shear force as per regulation
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
Vd = Design shear force calculated under increased vertical loads
Ve = Design shear force calculated considering earthquake code conditions
