As demands for freeform structure were gradually increased, researches about various shapes of claddings have been conducted. Particularly, claddings made from concrete easily made complex shapes. Because of this advantage, many researches about manufacturing methods and light weight of concrete mainly have been conducted. For example ALC (Autoclaved Lightweight Concrete) was the most popular claddings that had a great strength without aggregate and were cured at high temperature and pressure conditions. This paper showed multi-layer reinforcement system, exactly 5 layers polymer reinforcement method, that consisted of 3D printing material with low weight and high performance mechanical properties. Finite element analysis were performed to predict the maximum deformations loaded by wind and self-weight. Joints of analysis model were simplified as the pin joint. The variable of this analysis was the material arrangement of 3 layers located at center among exterior layer. Finally, the maximum deformations of analysis results were compared with the limitations of claddings.
