"The basis for the Fire Resistance Directory" (Various authors in Fire Technology or similar journals).

The 2018 edition is particularly significant because it reflects the building industry’s transition toward sustainability, lightweight construction, and open floor plans. It bridges the gap between legacy heavy masonry designs and modern light-gauge steel, engineered wood, and composite assemblies.

One of the most complex aspects of the UL Fire Resistance Directory is the classification of beams and floors as "Restrained" or "Unrestrained." Several papers critique or explain this aspect of the directory. "The basis for the Fire Resistance Directory" (Various

While every annual update adds new designs, the 2018 directory is notable for several trends: These documents bridge the gap between the raw

The 2018 directory is predicated on the standard fire test (ASTM E119 or UL 263). An assembly is mounted in a furnace, and temperatures are forced to follow a specific time-temperature curve (reaching 1,000°C / 1,832°F within one hour). To earn its rating, an assembly must satisfy four criteria:
