Seismic analysis of waste packages stacked in radioactive waste disposal silos

Comparative Studies between Frequency Domain Analysis and Time Domain Analysis on Free-Field One-Dimensional Shear Wave Propagation

“…Since the underground silo structure has been used for many purposes, various studies have been published on earthquake responses as well as structural safety of underground silos in many countries around the world. In particular, many research results have been published on the underground silo as a radioactive waste repository [1,12], the Although Korea has been recognized as a safe country for earthquakes, relatively large-scale earthquakes occurred in 2016 and 2017, respectively. The 2016 Gyeongju Earthquake (local magnitude (ML) of 5.8) and the 2017 Pohang Earthquake (ML of 5.4) were reported to have caused a lot of damage to many buildings and facilities in the surrounding area [8,9].…”
