PARAMETRIC ANALYSIS OF THE BUCKLING RESISTANCE OF THE SILO STEEL WALL

Abstract

The latest final draft amendment EN 1993-4- 1:2007/FprA1 brings a variety of changes that will apparently soon become valid. Present article deals with the issue(s) of silo steel wall design from the aspect of proposed changes related to the assessment of buckling resistance of the silo steel wall(s). The parametric analysis was performed according to the current standard, HRN EN 1993-4-1, and proposed amendment, EN 1993-4-1:2007/FprA1 by taking into account the silo fabrication quality parameter, as well as, the variations of the steel quality, wall thickness and wall curvature radius. The obtained results indicate that the new proposed amendment ensures a more realistic assessment of the silo steel wall buckling resistance. In that way the savings of material and economic benefit can be achieved easily.
