“…Meanwhile, the FEM method shows a pressure peak value of 98.8 kPa at almost 4 m above the cylinder-hopper joint. With regards to pressure, it is interesting to consider the results reported in steel silos by Louetri et al [17]. In fact, near the cylinder-hopper joint results are in good agreement with those obtained in the present work suggesting that the normal pressure increases drastically.…”

The present work investigates the reinforcement of concrete wheat-grain silos under initial damage. The reinforcement is achieved by mounting bands of carbon fiber reinforced polymer (CFRP) on the external walls of the silo. 4 modes of reinforcement are adapted according to the width of the band, the gap between two bands, the height of reinforcement and the number of layers achieved through banding. Analytical analyses were conducted using the Reimbert method and the Eurocode 1 Part 4 method, as well as numerically through the finite element software Abaqus. Results show that the normal pressure reaches a peak value when approaching the silo hopper. Initial damage in a concrete silo was first determined using a 3D geometrical model, while the damage analyses were conducted to optimize the CFRP reinforcement by mounting 2 CFRP bands close together above and below the cylinder-hopper joint. Increasing the number of banding layers could produce better performance as the damage was slightly decreased from 0.161 to 0.152 for 1 and 4 layers respectively.

“…This suggests that the use of CFRP can restrain the advent and expansion of cracks. The work reported by Louetri et al [17] enhances the interest of using CFRP in silos. They have presented a numerical analysis of the reinforcement of steel slender silos having concentric hopper with CFRP.…”

“…Kalantari and Razzaghi [3] performed a parametric study of the buckling capacity of cylindrical shells with vertical hardening and showed that the buckling capacity of the shells varies exponentially with the adjacent hardening spacing. Louetri et al [4] have conducted research on cylindrical silos in the hopper section reinforced by fiber reinforced polymeric (FRP) materials. In all cases examined, the use of FRP has been evaluated positively [5].…”

A B S T R A C TResearch on increasing the buckling strength of tanks carrying fluid and also cylindrical shells of thinwalled steel in civil engineering and mechanics is important. This is due to the widespread use of these structures in the industry. Due to the low thickness of the body and also due to the pressure forces entering these tanks, these structures are exposed to lateral buckling. In this research, the use of Carbon Fiber Reinforced Polymer (CFRP) rings to enhance and increase the buckling strength of tanks has been investigated. For this study, a tank with dimensions close to the actual tanks has been built and reinforced by a CFRP ring against the buckling. The results of the experiment indicated that the use of CFRP reinforcing ring considerably enhanced the buckling and post-buckling capacity of the tank. Further, comparing the results obtained from the experimental and numerical analysis and the values extracted from the theoretical relationships suggested that the results are in good agreement.
