Calculation Example – Buckling of Column (EC3).

Written by  TheStructuralEngineer.info

Check the column for buckling according to EC3. HEB300/S275 and axial force NEd=1000KN. The column (L=15m) is pinned at the two far ends (strong axis y-y). The column is pinned every 5m at the weak axis z-z.

 Solution

 We check that the section will not yield before buckling (not a class 4 Section).
