Integrated Fire-Structure Simulation Methodology for Predicting the Behavior of Structures in Realistic Fires
Publication: Structures Congress 2017
Abstract
This paper presents the numerical modeling of a test on a 6-meter-long steel W-section beam subjected to combined structural load and localized fire. An integrated fire-structure simulation approach was successfully applied to model the fire-thermal-structural behavior of the beam specimen. The difference ratios between the predicted and measured values for failure time, failure temperature and failure load can be as small as 0.7% (0.2 min), 2.9% (19 oC) and 9% (9 kN), respectively. In this paper, failure temperature is defined as the maximum temperature in the beam specimen at the onset of failure. Detailed description of the numerical models was presented. The study might serve as a validation case of the integrated fire-structure simulation approach which could be used in structural fire engineering design.
