Seismic Response of Elevated Steel Water Tanks Equipped with a Novel Steel Curved Damper
Year: 2025
Type: article
Abstract: This study explores the performance of a novel curved steel damper system in lessening the seismic response of elevated steel tanks. It specifically examines two types of 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 the dynamic characteristics and structural responses of the tank systems. The application of the curved steel damper, placed between the tank container and its supporting structure, resulted in a significant reduction in base shear forces and deformations of the tank walls when compared to traditional designs. The findings highlight the effectiveness of the damping system, showing that the curved damper leads to decreased maximum displacement and base shear forces during seismic activities. This research contributes essential knowledge for the seismic design of elevated steel tanks and proposes an innovative, cost-efficient strategy for enhancing their earthquake resilience.
