|| The rolling ball was covered
with a high damping material to lower the displacement
||The dynamic responses of the superstructure
resulting from either earthquakes or micro-excitations
can both be isolated by the BPS.
||The structure of the BPS is very simple.
The BPS is suitable for controlling the dynamic
responses of the attached equipment. (medical
facilities, sensitive apparatus, high-raised
floor and so on)
||The isolated facilities can operate normally
||The mechanical behavior of the BPS is stable;
therefore, no maintenance is required after
||The residual displacement of the BPS base
isolator after an earthquake is negligible.
