Home > T-BAGS seismic base isolation method > Summary of T-BAGS seismic base isolation method

T-BAGS is filled with sand in a special bag developed by our company.
T-BAGS Seismic Base Isolation Method uses two, layered sand bags with a special sheet placed in between them under the floor and foundation. In the event of an earthquake, the sand bags are able to freely slide and absorb the vibrations.

Concept of safe and secure T-BAGS base isolation method

Cannot be secured with "Will not damage / Will not collapse"

Simple seismic base isolation construction method similar to sandbags

Test to prove the effect of the T-BAGS base isolation method

"Compression testing by universal testing machine"

A picture of a load resistance testing by universal testing machine.

"Static test - cyclic shearing test"

A picture of static cyclic shearing test conducted with the assumed design load (vertical) of the building in order to check the hysteretic damping behavior of T-BAGS lateral cyclic load (earthquake).

"Dynamic test - Single way vibration table"

A picture of sine wave and seismic wave excitation testing conducted by mounting specimen composed of solid model frame and T-BAGS on horizontal single way vibration table.
