The purpose of this study is to present the suitable values of the hardness of school gymnasium floors from the viewpoint of safety in exercising and falling. Besides this study is looked upon as a pilot study for considering the methodology of studying the performances of building elements related to human safety. After considering the relationship between the result of questionnaire on the actual safety circumstances of school gymnasium floors and the physical characteristics of floors corresponding to the hardness measured by the pertinent measuring apparatus, following conclusions were obtained. (1) In the case of safety in exercising, clear correlations were estimated between the physical characteristics of floors and the using sense as well as the injury experience. Then the most suitable value of the hardness of school gymnasium floors was presented. On the other hand, in the case of safety in falling, the correlation between the physical characteristics of floors and the injury prediction was recognized, however, the degree of correlation between the physical characteristics and the injury experience was not sufficient. But the possibility of solving the problems was indicated and the upper limit value of the hardness was presented. (2) From the viewpoint of grasping the performances of building elements pertaining to human safety, the method adopted in this study was proved to be effective. Moreover, it was also proved that human sense on safety was available to the studies of safety.
