Abstract(J)E-ディフェンスは、実大 3 次元震動破壊実験施設の愛称である。これまで 113 課題の実験を完遂し、運用のノウハウも蓄積している。研究では、建物のモニタリングシステムの普及を見据え、非線形な減衰と剛性の時刻歴変動の同定手法の研究も実施している。ここでは、E-ディフェンス活動の概要について紹介する。


Abstract(E)E-Defense is officially called as “3-dimensional Full-Scale Earthquake Testing Facility” and has been operated as a shared facility from 2005. As of last year, we have completed 113 projects with gotten know-how of E-Defense operation skill without accident and trouble. Now, we’re summarizing know-how in a manual for the continuous operation. As for seismic research, we now focus on the development of structural health monitoring system to practically use and studying the nonlinear dynamics inversion method for identify the time-history of stiffness and dumping of structures dynamics under seismic shaking.
In this paper, presented the outline of E-Defense activities.

About search


How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
