چکیده مقاله
Thin walled cylindrical steel shells are commonly used in constructing different civil structures Steel silos and steel tanks are two important examples These shells may experience major axial compressive stresses during their service life Due to small wall thickness, they are potentially susceptible to axial buckling It is known that the buckling capacity is closely related to the shell wall thickness Corrosion shall reduce the thickness of shells in a uniform or non uniform manner It may also occur in local areas or involve all parts of the shell wall Accordingly, in the current paper as a preliminary study, the effect of corrosion considered by local thinning of the shell wall on axial buckling of steel cylindrical shells has been investigated To this end, non linear Finite Element FE analyses were used The results obtained highlight the detrimental effect of local corrosion on buckling resistance of these structures that may even surpass the other unfavorable effects such as imperfections
