Question: UKC , 3 5 6 4 0 6 2 3 5 b ) Figure 1 shows a 4 . 5 m S 2 7 5

UKC ,356406235
b) Figure 1 shows a 4.5m S275 column unrestrained along its length and pinned at both ends. The column carries an ultimate design axial load of 5000kN. Check the buckling resistance of the column by taking the effective length LCr=1.0L by considering the buckling will govern in minor axis z-z (Take buckling curve 'c').
Given properties:
Partial factors, YM1=1.0.
Young Modulus, E=210000Nm2
Radius if gyration, i=10.2cm
UKC , 3 5 6 4 0 6 2 3 5 b ) Figure 1 shows a 4 .
