The finite element method for evaluating the fire behavior of steel structures
Journal of Structural Fire Engineering
Article publication date: 30 August 2022
The purpose of this study is to contribute toward providing the main aspects of numerical modeling the fire behavior of steel structures with finite elements (FEs). The application of the method is presented for a characteristic case study comprising the series of large-scale fire door tests performed at the Danish Institute of Fire and Security Technology.
Following a general overview of current practices in structural fire engineering, the FE method is used to simulate the large-scale furnace tests on steel doors with thermal insulation exposed to standard fire.
The FE model is compared with the fire test results, achieving good agreement in terms of developed temperatures and deformations.
The numerical methodology and recommended practices for modeling the fire behavior of steel structures are presented, which can be used in support of performance-based fire design standards.
This research was partially supported by the Danish Institute of Fire and Security Technology (DBI) and the Innovation Fund of Denmark under Grant Agreement No. 9066-00031B.
