Experimental Evaluation and Numerical Simulations of Nanocoatings in Infrastructure Fire Applications
AbstractAlthough coating masonry walls with polymeric elastomers can mitigate the effects of a projectile strike in a blast or explosion, it may also increase the fire hazard to the structure and the occupants. Although a rigorous assessment of this problem would require full-scale fire tests, considerable insights can be gained by performing bench-scale tests in conjunction with computer simulations. A joint experimental/numerical methodology is presented in this paper to evaluate the extent to which blast-resistant coatings, applied on masonry walls, may contribute to the spread of existing fire. The experimental data are obtained by performing cone calorimeter heat release rate (HRR) measurements. Flammability characterization and the heat flux generated for structural systems and components that are coated with blast-resistant and fire-retardant polymeric coatings are performed using the NIST fire dynamic simulator (FDS). In these simulations, structural concrete columns and masonry walls are exposed to an assumed fire. The results presented in this paper could be employed in coupled thermal/structural finite element analysis to assess the performance of concrete members coated with polymeric materials and subjected to fire loading.
