Where necessary the punching shear resistance outside the shear reinforced 4.3.4.5.2(3) area should be checked by considering further critical perimeters.

Therefore distance from column face

This would be approximately at the next critical perimeter taken to be at a BS 8110 distance 0.75d beyond the previous one. No further shear reinforcement Figure 3.17 required.

The tensile reinforcement (T16 @ 150 mm crs.) should extend for a full anchorage length beyond the perimeter at 420 mm from the column face.

Column A/1 (300 mm x 300 mm corner column)

Critical perimeter located at 1.5d from face of column (see Figure 4.18). 4.3.4.1(3)

Figure 4.18 Critical perimeter at corner column u = 600 + 277tt/2 = 1035 mm VL = 0.41 x 156.4 = 64.1 kN
