Recently, buildings using seismic isolation system (SIS) become general to improve seismic safety in Japan. However, the SIS general is chiefly effective only to the hori [...]

The three dimensional(3D) seismic base isolation system for applying to the civil building have been proposed in Part 1. In this paper, test results for confirming mechan [...]

Whether smart structures can be applied to large-scale structures on the earth or not, depends on performances and costs of actuators. Therefore, it is suitable that piez [...]

Many base-isolated buildings have been constructed using passive isolation systems with the purpose of reducing response accelerations of superstructures during earthquak [...]

About 8 months after the October 23rd, 2004, Mid-Niigata Earthquake, the middle reach of the Uono River was flooded in a heavy rain. The flood-ravaged zone was immediatel [...]

As the semiconductor processing technology keeps evolving, the demand for vibration-free environment of semiconductor manufacturing facilities keeps becoming severe. We d [...]

This paper describes a seismic isolation system for monocrystal pullers. In a monocrystal puller, a monocrystal is suspended by a wire through an extremely narrow neck, a [...]

In developing countries of seismic area, many people have to live in traditional masonry houses of stones, bricks and concrete blocks. Though collapse of the houses is on [...]

A lot of researches on the seismic vibration control system show that they have effect on mitigating seismic damage. Most researches on structures with damper devices sub [...]
