Steel-Concrete Composite Floor Systems Subject to Fire, Phase 2
Research Overview
The multi-year experimental research project is being conducted on full-scale composite floor systems under realistic large enclosure fires simulated with natural gas burners at the NIST National Fire Research Laboratory. The present test program is aimed at generating technical information and data essential for the development and validation of predictive tools and advancing fire safety design and assessment for steel-framed buildings.
