DEVELOPMENT OF TOPOLOGY ANALYSIS TOOL FOR REINFORCEMENT OF FLOOR SLAB USING CFRP(Structure)

The topology optimization tool for reinforcement of floor slab using CFRP plates is developed. This tool is used to find an efficient layout of CFRP plates on a floor slab. The floor slab reinforced by CFRP plates is modeled by a laminate plate. The laminate plate is analyzed by FEM using solid element. The CFRP layer is separated by a necessary part and an unnecessary part using topology optimization method. The density method is adopted for the topology optimization analysis. By using such tool for the reinforcement of floor slabs, it is possible to efficient reinforcement using CFRP plates.
