Integrating Structural Fire Analysis with Hybrid Fire Testing: A Framework for Enhanced Stability, Software development and Full-Scale Evaluation.
Abstract Understanding how structures behave in a fire is becoming increasingly important as engineers move toward performance-based design. Conventional fire-resistance tests evaluate isolated components under simplified and constant boundary conditions, and numerical models remain constrained by …

Intumescent formulations incorporating melamine phosphate
Once familiar with the fire test rig constructed by M Kay, and modified to allow incorporation of both video and computer facilities, Melamine Phosphate production was scaled up from small to large laboratory scale, and then commercial scale production was considered. Samples produced at each stage …

Bench Scale Characterization of Joints and Coatings
… large-scale test used to qualify assemblies for fire resistance, including heat transmission and structural integrity. The test requires specialized furnaces and full-scale assemblies that are 3.0 m (10 ft) or more on each side, making it very expensive to perform. In this study, we investigated …

Response of high strength concrete columns under fire-induced biaxial bending
Reinforced concrete (RC) columns, under fire conditions, can experience biaxial bending which can arise due to eccentricity in loading, uneven spalling, or due to significant thermal gradients generated through 1-, 2-, or 3-sides of fire exposure. High strength concrete (HSC) columns are especially …
