Abstract:

North American and Eurocode design methods for fire-resistive exposed wood members provide a very good example of the translation of research into practical engineering design procedures. Assuming identical loads, the North American design method for beams yields results that are very close to those of the European methods. For columns, the North American method overestimates fire endurance times if failure is due to bucking, while underestimating the fire endurance of short columns exposed from 4 sides. More detailed comparisons between the two design methods and experimental data are needed before recommendations can be made on how to resolve the discrepancies.
