Abstract

This paper presents a novel method of strengthening cylindrical shells by applying a thin layer of fibre-reinforced polymer (FRP) composite, used at the silo body, can effectively eliminate the problem and increase the buckling strength. The strengthened shell is analysed using finite element method (FEM) in this preliminary study. The method of strengthening with GFRP has been used in many studies recently. Therefore, it was decided to conduct this research. In this study, as a result of the reinforcement made by wrapping 2 mm thick GFRP fabric into the 12 m height Steel silo structure. The differences between modal parameters of the steel silo and GFRP reinforced Steel silo were compared. These modal parameters are period and mode shapes. The first 5 modes of the situation with and without GFRP were examined with finite element method. A difference of 2% - 10% was observed in the periods of the first 5 modes. Reinforcement with GFRP has been observed to be positive effects for safety on the steel silo. GFRP reinforcement method can be used for safety in steel silos.
