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.

Abstract
In this paper, the research program “Optimized use of intumescent coating systems on steel members” is presented. The aim of the project is to quantify the influence of space-enclosing elements on the thermal behavior of supporting steel members. Those elements partially result in a restrained expansion of the fire protection system. Experimental investigations on coated beams and columns directly connected to space-enclosing elements are presented. Additionally, numerical simulations are performed for temperature field calculations of steel elements with intumescent coating. As a new development, the numerical model takes into account the expansion process of the intumescent coating.
