Since the possibility of Tokai or Nankai earthquakes, the reinforcement of the buildings is very important. The method using the CFRP tape is effective for the reinforcement of the floor slab. However, since it is relatively expensive, it is necessary to efficiently affix for the CFRP tape. Therefore, in this paper, the topology optimization method (density approach) is used in order to obtain the optimum layout of the CFRP tape. For this purpose, the FEM program for analyzing the laminate plate is developed, and the density approach with CONLIN optimizer is applied. In this program, the solid element based on the hybrid method is used instead of the conventional plate element. In this study, the void slab is used for the floor structure. The effectiveness of the proposed method is shown by the numerical examples and the comparison with the experiment.
