Fire resistance design of japanese traditional floor-beam assemblies based on the prediction of bending stress in the timber beam - An experimental study

Abstract

Assessment of the mechanical fire safety performance of Japanese traditional floor amassembliesis conducted by predicting the post fire bending stress of timber beams and validated by full scale 45 minutes furnace tests with specimens of floor beam assembly of different spans and intervals of the beams.The study intends to explore the possibility to widen the application of and to develop the oretical method for the design of traditional wood enconstrtion. It has resulted in the prediction of the fire safety performance of floor-beam assemblies by this method closer to reality than those by the conventional deformation-based assessment.
