Experimental determination of fire resistance of steel elements (X-brace) protected with intumescent paint

  • 1 Academy of the Ministry of Interior - Sofia, Bulgaria

Abstract

The report presents and analyses data from tests of steel elements with different cross sections (massivity factor) protected with three different coating thicknesses. The obtained results are presented in graphics. Comparisons between the different protections in terms of fire resistance are made. The tests are part of a large-scale study of the behaviour of the same steel sections with applied reactive protection – intumescent paint (this report) and passive protection – plasterboard and rock wool.
