Summary:To provide a strength display system and a strength display method for wooden structural materials of buildings, capable of understanding to which degree a strength of a wooden structural material being degraded by heat actually deviates off a calculated numerical value, in a more realistic and accurate manner.SOLUTION: A ratio of first numerical data in the following (1) for a beam to second numerical data in the following (2) for a beam corresponding thereto is made to be displayed in a display screen. (1) The first numerical data is obtained through which: a prescribed combustion condition is set; a portion assumed being combusted under the combustion condition is considered as a burned allowance; a strength of a wooden structural material is calculated, based on modified dimension data of the wooden structural material in which the burned allowance portion is excluded from the dimension data of the wooden structural material, and strength calculation data. (2) The second numerical data is obtained through which: a plurality of wooden structural materials, each of which has a different dimension and burned allowance pattern, is burned in a different prescribed combustion condition; and an actual strength of the wooden structural materials left in an unburned state is measured.SELECTED DRAWING: Figure 1 【課題】熱で低下した木質構造材の強度が実際にはどの程度計算上の数値からずれているかをより実際に即した正確さで把握することができる建築物の木質構造材の強度表示システム及び強度表示方法を提供すること。【解決手段】ある梁の下記(1)の第1の数値データと、それと対応する梁の下記(2)の第2の数値データとの比を表示画面に表示させるようにした。(1)所定の燃焼条件を設定し、その燃焼条件で燃えたと仮定した部分を燃え代として木質構造材の寸法データから燃え代部分を除いた木質構造材の修正寸法データと強度算出用データに基づいて当該木質構造材の強度を計算して得られた第1の数値データ。(2)寸法と燃え代パターンのそれぞれが異なる複数の木質構造材を、異なる所定の燃焼条件で燃焼させ、燃え残った状態の木質構造材の実際の強度を測定して得られた第2の数値データ。【選択図】図1
