The basic requirement is that the moment capacity at the notch in<br />

the presence of shear must be greater than the moment from the<br />

product of the end reaction and the distance to the end of the notch.<br />

M ≥ F ( t + c)<br />

cn v<br />

t1 is the gap<br />

c is the notch length<br />

Check for low shear<br />

Fv £ 0.75Pv<br />

from previous calculation 4.2.5.4<br />

Pv = 394.8 kN<br />

\ 0.75Pv = 296.1 kN<br />

110 kN < 296.1 kN<br />

Z = elastic section modulus of the residual tee-section at the notch<br />

= 13. 2 kNm<br />

102.6 kNm > 13.2 kNm<br />

Therefore the moment capacity of the notched beam is adequate.<br />
