Popis:	In this study, we are attempting to develop fireproof construction that consists of common wood species without any inorganic layers. The specimens we suggest are glued laminated lumbers that have flaming-die-out layer consisting of fire-retardant wood between the surface layer and the core zone. Fire-retardancy is provided by treatment with fire-retardant chemicals. We carried out fire resistance tests and loaded fire resistance tests on several types of Japanese cedar (Cyptomeria japonica D.DON) column specimens. As a result, we demonstrated the column specifications that have 2-hour fire-resistance performance. We confirmed the usefulness of utilizing the laminas impregnated with fire-retardant chemicals as flaming-die-out layer.
