Abstract
Shape memory alloys are designed to revert to their original state due to stress and heat, as well as to enhance ductility, energy absorption, and damping capabilities for significant deformations. Fatigue caused by cyclic loading with high frequency is of paramount importance for controlling deformation, drift, and the initial state of the material, as well as structural stability. Therefore, studying their behavior under loading cycles and qualitatively and quantitatively assessing their effectiveness in reducing deformations and parameterizing this effect becomes essential for optimizing structural behavior using SMAs. Given the significance of these materials in the construction of concrete tanks, this research focuses on analyzing SMA components, specifically investigating the effects of smart materials. The scope of the SMA is limited, and consequently, this study examines a concrete tank model utilizing smart materials aimed at enhancing SMA performance. The conclusion of this research indicates that the use of smart materials will positively affect the structural behavior.

Investigation of the effect of SMA smart materials for the construction of concrete tanks under finite element analysis

Highlights

  • Moment Reduction: Placing the damper in the concrete storage tanks reduces the moment at the base of the structure by 31%.
  • Axial Force Reduction: The inclusion of the damper results in a 92% reduction in the axial force at the base of the column due to earthquake forces.
  • Stress Reduction: The use of the damper leads to a 91% reduction in the stress developed in the structure.
  • Strain Reduction: Incorporating the damper results in a 14% reduction in the strain developed in the elevated concrete tank structure.
