Abstract :
Buckling instability is the most important factor at columns failune. Icauses large deflection and mostly is analysed by first yield criterion. Due fo some difficulties in application of the criterion, soecially in inelastic columns, a new method, namely geometric criterion is introduced in this paper to improve the buckling analysis of real columns. In this research project a number box- section columns are designed and tested until the buckling failure is reached. The slenderness ration in the specimens are selected so to fit with the manufactured columns in steel structures.
