Abstract
The large-scale shaking table in Tsukuba owned by National Research Center for Disaster Prevention, which was completed in 1970 after the 1964 Niigata Earthquake, will be closed in 2022. The table has an area of 15m × 15m and a exciting force of 360tons. The table was called as first large-scale shaking table. In 1970, the table was completed as one direction shaking table horizontal or vertical switching with stroke 60mm. In every year, several experiments were conducted. In 1988, the shaking table performance was improved. After Kobe Earthquake Damage, many shaking tables of high performance have been constructed. And it became clear that the seismic records exceeded 10m and 3m/s. Considering this situation, it must be said that the performance of the Tsukuba shaking table, which has been 50 years since its completion, has become difficult to meet the demands of the times.
In this paper, it will be described the process of determining the construction specifications for the Tsukuba Shaking Table and the results of the main experiments conducted over 50 years, and this is the final word.
