Research and Development of Three-Dimensional Isolation System for Sodium-Cooled Fast Reactor: Part 6 — Development of High Speed Oil Damper for Isolated Building

Autor: Masashi Miyazaki, Takahiro Somaki, Masato Uchita, Tsuyoshi Fukasawa, Shigeki Okamura, Satoshi Fujita, Tomohiko Yamamoto, Takayuki Miyagawa

Publikováno v: Volume 9: Seismic Engineering.

The design of seismically isolated structures has been required not only for damping devices with large damping capacities but also for those with high allowable velocities. This is because the seismic response assessment has been conducted using var
