THICKNESS DETERMINATION FOR SPRAY-APPLIED FIRE RESISTIVE MATERIALS

摘要

Following The World Trade Center disaster, a review of current design practices has commenced with hope that out of the tragedy something may be gleaned that could influence more effective new building designs. Fireproofing is a legitimate area of focus. There is little debate that a more rational approach to fire protection is possible than our current reliance on the prescriptive method using tested assemblies. Efforts are being expended to formulate a rational approach for evaluating the performance of steel structures in a fire environment and a more rational performance based approach to fire protection is certainly on the horizon. Nonetheless, the design team is faced with providing fire-safe buildings under current guidelines. A review of the method for determining the thickness of spray-applied fire resistive material based on the current prescriptive code approach is addressed in the following.
