It was researched the ultimate bearing capacity of H steel columns under axial compression by means of FE software. The results shows that the residual stress peak in the flange and has the biggest effect on the H steel column,the stress peak at the midpoint of the flange has a less effect,and the peak effect is the minimum in the midpoint of the web. the stability factor of Q550 high strength steel components by the existing design code of steel structures is slightly conservative.
