STUDY ON VERTICAL RESTORING FORCE DEVICE USING DISC SPRINGS

The authors developed a three-dimensional seismic isolation system to ensure performance in the vertical and horizontal directions. This is required for large-scale disc spring achieve both support functions. Additionally, two methods are required: one control variance of restoring force, other predict using response analysis. paper describes an optimal combination method springs absorb caused by manufacturing process calibrating metaheuristic algorithm. Moreover, identify variables hysteresis loops combined proposed applicability these verified static loading tests data obtained that expands dimensions defined JIS B 2706:2013 ISO 19690-1:2017. were conducted 72 with 350 mm diameter six−disc 700 diameter. demonstrates can force accurately efficiently.
