Abstract
Topology optimization is used as a tool to aid the reinforcement design of concrete slabs with carbon fiber reinforced polymers (CFRP), based on increased load capacity. Topology optimization is used to locate the region of application of the reinforcement. The theoretical and practical aspects of reinforcement design are discussed. Numerical simulations are performed using the finite element method concomitantly with the automated optimization procedure. The Density Method, a simple, efficient and robust approach, is used in the optimization technique. A discussion is given about the similarity of topology optimization criteria for maximizing the stiffness and strength of the structure. The applications of this technique are compared with the conventional technique for strengthening concrete slabs. By optimizing the distribution of the reinforcement, the aim is to minimize the quantity of material, thereby reducing costs. The obtained results show that the topology optimization can be an effective tool to support the reinforcement design in concrete structures.
