NFPA 557 PDF

Stay up to date with NFPA 557, Standard for Determination of Fire Loads for Use in Structural Fire Protection Design, for the latest criteria for structural fire engineering of buildings.

Having a clear understanding of how to calculate the fire load in a building is a needed element when considering structural performance under thermal exposure. NFPA 557, Standard for Determination of Fire Loads for Use in Structural Fire Protection Design, provides a methodology for deciding the fire load and fire load density to be used as the basis for the evaluation and design of the structural fire performance of a building.

Developed to address the need for guidance and standardization in the area of structural fire engineering, NFPA 557 covers:

• Design fundamentals
• Development of fire loads
• Occupancy-based fire load density
• Survey method-based fire load density
• Documentation, inspection, and maintenance
