This study explores the performance of a novel curved steel damper system in lessening seismic response elevated tanks. It specifically examines two types tanks, broad and tall, by analyzing their behavior during past earthquakes. Non-linear time history analyses were executed using various ground motion records to evaluate dynamic characteristics structural responses tank systems. The application damper, placed between container its supporting structure, resulted significant reduction base shear forces deformations walls when compared traditional designs. findings highlight effectiveness damping system, showing that leads decreased maximum displacement activities. research contributes essential knowledge for design tanks proposes an innovative, cost-efficient strategy enhancing earthquake resilience.

U-shaped seismic dampers, passive metallic devices that dissipate energy by cyclic plastic deformation, are designed to mitigate the effects of loads on structures. This study focuses development an advanced computational model a damper, chosen for its unique design variable thickness and width, which contributes superior performance. The simulation uses nonlinear finite element analysis bilinear hardening calibrated actual stress–strain curve low-carbon steel. To ensure accuracy, rigorous mesh convergence is performed quantify numerical prediction errors establish suitable predicting local deformation phenomena, including strain stress fields, throughout displacement-based loading protocol. Mesh sensitivity analysis, examining equivalent cumulative strain, derives damper hysteresis confirms criteria within experimentally observed response range material. resulting novel contribution provides reliable predictions inhomogeneous dissipation, essential optimizing performance through more sophisticated damage-fatigue models guarantee lifetime damper.
