The isolation period of the TFPS
isolated structure along two perpendicular
directions can be designed differently. |
| 02. |
TFPS is suitable not only as a base isolator
for the heavy full-scale
structures (thousands tons of axial load),
but also for equipments in high-tech facilities,
hospitals, museums, historical buildings etc. |
| 03. |
The isolation period is dependent only on
the radius of curvature of the concave surface.
The isolation period of 3~5sec is easy to achieve
for a TFPS isolated structure; however, it
could be extremely difficult to achieve for
a base isolated structure with LRB and HDRB. |
| 04. |
The Teflon-composite with low friction coefficient
coated on the sliding surface of the MFPS base
isolator possesses a good durability under
thousands cycles of reversal loading. The maximum
friction coefficient at a high velocity is
always less than 0.12. |
| 05. |
TFPS has an excellent earthquake-proof efficiency
whether it is subjected to near fault earthquakes,
strong ground motions at soft soil-deposit
sites or ground motions at basins. (The displacements
response of the LRB or HDRB could be remarkable
in these conditions) |
| 06. |
The fireproofing capability of the TFPS base
isolator is the same as that of the columns,
beams, panels and floors of a structure. |
