Which table addresses fire-resistance ratings for building elements?

• A. Table 504.3 Allowable Building Height in Feet Above Grade Plane
• B. Table 722.24 Minimum Dimension of Concrete Columns
• C. Table 1004.5 Maximum Floor Area Allowances per Occupant
• D. Table 601 Fire-Resistance Rating Requirements for Building Elements

Answer: (D)

Understanding fire-resistance requirements for building elements is about knowing where the code tells you how long elements must resist fire. The table that addresses this compiles the required fire-resistance ratings for different building elements (such as bearing and nonbearing walls, floors, roofs, and structural members) based on construction type and the element’s role. It gives the specified durations in hours, so you know, for example, how long a wall or floor assembly must resist fire to meet code for a given occupancy and construction type. This table is the go-to reference whenever you need to verify that an element’s fire resistance is compliant, before detailing assemblies and verification tests.

Other tables cover different topics: one sets allowable building height, another states minimum dimensions for concrete columns, and another addresses maximum floor area per occupant. These are unrelated to fire-resistance needs, which is why they don’t provide the necessary guidance for fire-rated assemblies.
