THE FEATURES OF DETERMINATION OF SEISMIC LOADS ON STEEL SILOS WITH A FLAT BOTTOM ACCORDING TO DBN V.2.6-221:2021

Abstract

The article is devoted to the peculiarities of determination of seismic loads on steel 
silos with a flat bottom according to newly introduced DBN B.2.6-221:2021, harmonized with the 
global  system  of  European  codification  Eurocode.  The  main  focus  is  on  the  general  methods  of 
specifying seismic action and the principles of schematizing seismic action for analysis silos. The 
parameters of the acceleration spectra of the horizontal and vertical components of seismic load and 
their influence on formation of silos reaction in these directions are analyzed. The recommendations 
are given for accurate evaluations the inertia-stiff characteristics of silos with a flat bottom in height 
based  on  the  analysis  of  their  design  features  and physical  and  mechanical  characteristics  of  the 
particulate material.
