Shaking Table Pounding Test of a Novel Bidirectional Restrainer Using a Dual-Oscillator Loading Device
Abstract
This study evaluates a novel bidirectional restrainer for seismic pounding mitigation in hydraulic structures, aiming to establish reliable finite element modeling strategies and quantify its dynamic load capacity. An innovative dual-oscillator shaking table test, employing direct F = m × a force calculation, was developed and validated. Key findings reveal that the restrainer’s dynamic tensile and compressive stiffnesses were calibrated as 49.6% and 26.2% of its static values, with load capacities exceeding 2.25 and 2.49 times the design loads, respectively. The validated finite element method provides a critical tool for performance evaluation, supporting the restrainer’s application in seismic design.
