Comparison of BS and EC2

Span 6m Will consider beams for comparison of BS and EC2

Section 300x600mm
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
How = 1946 mm2 How = 1626 mm2
How = 33 mm2 A = 0mm2
R/F Scissors
T10 @ 285mm center distance		 R/F Scissors
T10 at 415 mm center distance
