It is about.

Seismic technology, seismic isolation technology, and vibration suppression technology are applied to ensure the safety in response to earthquake, and seismic isolation technology is used for seismic isolation targets (various facilities, equipment, devices, devices, etc.) Seismic performance is ensured by separating the natural frequency / period, and it is a technology to reduce the seismic force acting on the seismic isolation object.

Here, the conventional seismic isolation technology applied to small objects includes a spring device of low frequency, laminated rubber having elasticity, laminated rubber including lead / tin, pendulum bearing device including a curvature plate and a sphere of a predetermined size, Linear guide devices having low friction, or a combination of these devices are used.

On the other hand, the seismic isolator is different in structure shape, material, and dynamic characteristics, but it is generally accompanied with a large deformation because it is designed to have a lower seismic frequency than the frequency band of the general earthquake. In fact, in Japan and other countries, displacements exceeding the limits that can be realized in an earthquake occurred, causing the equipment and equipment mounted on the top to fall, and also causing damage by colliding with adjacent structures. Accordingly, it was required to prepare a plan to measure and manage the dynamic behavior of the seismic isolator in real time, and to confirm the magnitude of seismic force generated and the normal operation of the seismic isolator in case of an earthquake damage. In addition, it was necessary to record the dynamic behavior of the seismic isolator and use it for analysis after the disaster.

The system for measuring the displacement of the superstructure of the bridge is a technology that can measure the relative displacement of the upper and lower parts of the seismic support of the bridge through an external measuring frame, and is difficult to apply when a small seismic isolator is introduced. There was a drawback that the strain measurement was possible only in the axial direction.
