FIRE-RESISTANCE DESIGNING METHOD FOR BUILDING AND FIRE-RESISTIVE BUILDING

PROBLEM TO BE SOLVED: To obtain a required fire-resistive performance while reducing a cost for a fire-resistive treatment, aiming at the drop out of fire-resistive equipment using glass such as wired glass in an actual fire. SOLUTION: The time up to the drop out of fire-preventive equipment using glass after the generation of the fire is computed, and the duration of an indoor fire after the drop out of the fire-preventive equipment using glass is computed regarding a fire chamber with the fire-preventive equipment using glass. The time up to the drop out of the fire-preventive equipment using glass after the generation of the fire and the duration of the indoor fire after the drop out of the fire-preventive equipment using glass are added up regarding the fire chamber. The added-up indoor fire duration of the fire chamber is computed while computing the retention fire-resistive period of a member facing the fire chamber, and the member and a fire-resistive covering thickness are adapted so that the added-up indoor fire duration reaches the computed retention fire-resistive period or less.
