Summary
Timber elements, which are different from other structural elements, have a characteristic problem in that the load bearing capacity decreases due to self-burning in the case of a fire, and this self-burning may continue after other fuel in the room has been exhausted. Therefore, the structural fire performance of timber elements should be clarified during not only the heating phase, but also the cooling phase. However, in examining the load bearing capacity of timber elements in a fire, few studies have considered the cooling phase. In the present paper, the fire performance of glued, laminated timber beams is discussed based on load-bearing fire tests that take the cooling phase into consideration.

Summary
Fire-resisting wood structural elements for building were developed. It is composed of three layers made of glued laminated timber, “a load-bearing part, a self-charring-stop and a surface layer”. Tree species of load-bearing part is limited to the only kind. In order to enable a species different, this research was carried out. Fire resistance test was performed to demonstrate the effect on fire resistance of the wood density. The relationship of fire resistance and wood density of the load-bearing part was clear. Usage of high wood density of the load-bearing part was obtained a conclusion that is advantageous to fire performance.
