Outline of Annual Research Achievements

当初の計画通りのヴォールト床を持つ試験体の作成が完了した。すでに振動台実験遂行に関して共同研究者モザキス准教授と打ち合わせを行い了承済みである。実験計測計画に関しては研究分担者新津教授と打ち合わせを行い、3次元画像計測システムとMEMS加速度計を組み合わせた計測計画に合意した。無補強試験体の実験後、修理・補強を施した試験体に再び実験を行う。

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

感染症拡大の影響により中断の期間があったものの2024年度中に完了させる準備が整ったため。

Strategy for Future Research Activity

上記の通り2024年度中に完了する研究課題であり、完了までの計画を分担研究者、国際共同研究者と合意済みである。
