ASCE/SEI/SFPE Standard 29-05 provides the most current and proven methods for calculating the fire resistance of selected structural members and barrier assemblies using structural steel, plain concrete, reinforced concrete, timber and wood, concrete masonry, and clay masonry. These methods present architects, engineers, building officials, and others with calculations for the equivalent fire resistance achieved in the ASTM E119 standard fire test. Topics discussed in this work include standard calculation methods for structural fire protection as well as standard processes for determining the fire resistance of plain and reinforced concrete construction, timber and wood structural elements, masonry, and structural steel construction. This Standard, a thorough revision of SEI/ASCE/ANSI Standard 29-99, is a joint effort between the Structural Engineering Institute (SEI) and the Society of Fire Protection Engineers (SFPE).
