Abstract

Abstract : Purpose: This paper aims to present numerical investigations regarding the heating behaviour of steel elements protected by an intumescent coating with an adjacent trapezoidal steel sheet. Design/methodology/approach: For this purpose, a three-dimensional numerical model of a coated I-section profile is developed in Abaqus taking into account the restrained foaming process of the intumescent coating due to the adjacent member explicitly. Findings: After the validation of the numerical model against own fire tests, the steel temperatures of a coated I-section profile with and without an adjacent trapezoidal steel sheet, resulting from fire exposure according to ISO-834, are compared to demonstrate the influence of the steel sheet in detail. Originality/value: The main objective is to evaluate the influence of an unprotected trapezoidal steel sheet on the temperatures of coated I-section profiles.
