Bridgestone Substantiates Durability of Its Seismic Isolation Rubber

on September 1, 2016 in Products

Bridgestone Corp. (TYO:5108) has been conducting performance verification testing of its seismic isolation rubber bearings together with Takenaka Corp. at one of the general contractor’s buildings. The isolators demonstrated long-term durability after being in place for approximately 30 consecutive years. Manufactured in 1986 from laminated natural rubber, the bearings have been in use at a Takenaka staff dormitory, located in...

Seismic Isolation Rubber Use Spreads in Japan, Adoption Rates Differ by Region

on June 14, 2016 in Products

When the Great East Japan Earthquake occurred in 2011, its hypocenter some 70 kilometers off the coast of Sendai City, Miyagi Prefecture, buildings were left devastated. However, this was primarily the result not of the 9.0 magnitude earthquake itself, which many buildings were able to withstand, but of the subsequent tsunami. As a method of addressing seismic activity, the use...

Kumamoto Earthquake Proves Seismic Isolation Rubber Effective

on June 14, 2016 in Products

The aftershocks continue from the major earthquake that struck the Kumamoto Prefecture on the Japanese island of Kyushu April 14. Almost two months after the original quake registered a seismic intensity of 7, an aftershock of intensity 5- struck on June 13. Although it cannot be said that the 24 buildings in Kumamoto Prefecture that incorporate seismic isolation rubber came...

Tokyo City University Develops New Seismic Isolation Rubber

on June 7, 2016 in Innovation, Materials

A research team at Tokyo City University has succeeded in developing a new seismic isolation rubber for use in new buildings that could have roughly twice the earthquake mitigation performance of structures using conventional materials. Led by Prof. Isao Nishimura of the architectural faculty in the university’s engineering department, the team is moving ahead on joint development with a manufacturer,...

Seismic Isolation Rubber Proves Highly Effective in Kumamoto Earthquakes

on May 27, 2016 in Industry, Market Background

Seismic isolation rubber alleviates the destructive force of earthquakes. And it does so with isolation components, manufactured from laminated rubber and other materials, to take the brunt of the seismic motion. So a relevant question is how buildings with seismically isolated structures faired during last month’s earthquakes in Kumamoto, Japan. Along with taking a look at conditions in post-quake Kumamoto,...
