Explosion and Fire Analysis of Steel Frames Using Fiber Element Approach
Publication: Journal of Structural Engineering
Volume 130, Issue 7
Abstract
Since the September 11th terrorist attacks, the research and engineering communities have given significant attention to building performance under combined effects of impact, explosion, and fire. This paper presents a numerical approach for inelastic transient analysis of steel frame structures subjected to explosion loading followed by fire. The approach adopts the use of beam–column element and fiber element to enable a realistic modeling of the overall framework subjected to localized explosion and fire. Detailed requirements for modeling elasto–plastic materials subjected to elevated temperature and high-strain rates are presented. Verification examples are provided. The influence of blast loads on the fire resistance of a multistory steel frame is studied.
