요약2 Finite element method and the tables of orthogonal arrays were used to reduce the floor impact vibration of the reinforced concrete slab in the apartment buildings. At first, previous experimental results showed that sound peak components to influence the rating of floor impact sound insulation were coincident with natural frequencies of the reinforced concrete slab, and there was a high linear relation between floor impact vibration and sound. In this study, to reduce the floor impact vibration the tables of orthogonal arrays were used for finite element analysis with 3 factors related to material properties and 5 factors related to slab shape parameters, and its results were analyzed by statistical method. The most effective factor among slab shape parameters to reduce the floor impact vibration was the length of living room and the floor impact vibration was predicted by 41% reduction in the acceleration peak by the optimal design values of the factors.
