Criteria for Building Size and Type, Jointing Buildings, and Fire Resistance Requirements

Building type is defined by criteria like square footage, occupancy, and number of floors, as outlined in chapter five. To manage size restrictions, a technique called jointing is used where a large building is divided into structurally independent segments. Fire doors and breaks are essential components of jointing to maintain fire safety standards. In seismic areas, specific requirements, such as accommodating seismic joints and fire-rated sheeting, may vary, but not all jurisdictions require fire-resistant floor sheeting according to the code. Wood frame structures like type three and type five may have combustible floors, although some areas may mandate fire treatment around the perimeter.
