Numerical simulation of the heating behaviour of steel profiles with intumescent coating adjacent to trapezoidal steel sheets in fire
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.
