Concrete quality 25 N/mm 2
Steel yield strength 500 N/mm 2
Dead load 30 kN/m
Traffic load 20 kN/m
| BS 8110 1997 | EC2 |
|---|---|
| Project load 1.4*35 + 1.6*20 = 81kN/m |
Project load 1.25*35 + 1.5*20 = 73.75 kN/m |
| bending moment wl^2/8 = 81 * 6^2/8 = 364.5 kNm |
bending moment wl^2/8 = 73.75 * 6^2/8 = 331.9 kNm |
| shear force wl/2 = 81*6/2 = 243 kN |
shear force wl/2 = 73.75*6/2 = 221.25 kN |
| K = 0.159 > 0.156 = K' R/F compression required |
K = 0.145 < 0.167 = Kbal R/F compression not required |
