strength steel structure and stability of the difference between what contact?

　　Hainan Steel tells you: strength steel structure and stability of the difference between what contact?
Of construction elements, strength calculation is a basic requirement, but steel construction elements, stable accounting is more important than strength calculation. Strength and stability in doubt although doubt belong to the first extreme state of doubt, but the difference between the two concepts. Maximum internal force or intensity questions concern the maximum stress in the structure member section whether the strength of the resulting cross-section bearing capacity or materials, therefore, doubt that the stress intensity doubt; doubt is to identify stable between internal resistance and structural effects the unstable equilibrium state, namely the state of deformation began rapid growth, are deformed doubt.
