Structural Guide

Structural loads, structural analysis and structural design are simply explained with the worked example for easiness of understanding. Element designs with notes and discussions have added to get comprehensive knowledge. Also, construction materials, shoring system design, water retaining structures, crack width calculations, etc. have discussed in addition to other aspects. 

Comparison of BS and EC2

Span 6m span beam consider for Comparison of BS and EC2

Section 300x600mm
Concrete Grade 25 N/mm2
Steel Yield Strength 500 N/mm2
Dead Load 30 kN/m
Live Load 20 kN/m

 

BS 8110 1997  EC2
Design Load
1.4*35 + 1.6*20 = 81 kN/m
Design 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’
