The Main Equipment and The Development Program
| １．The Main Equipment |
【Experimental System for Large Structural Models】
Static/dynamic load and displacement can be applied to the models. In addition,
pseudo-dynamic testing also can be executed by connecting the computer
with this system through GP-IB and the Internet.
The loading exuipments are as follows.
