||X-RADAS provides additional stiffness to
reduce seismic responses of the lateral displacement,
story drift, and torsion of structures during
||X-RADAS provides maximum energy-dissipation
capacity during the peak seismic response of
||The periods of the structure can be shifted
by using the yielding of X-RADAS to prevent
the occurrence of resonance.
||X-RADAS can be installed in a structure either
with steel bracings or RC walls. It is not
interfere he ambient light and the indoor space.
||Steel plates such as ASTM A36, A572 Gr. 50
and LYS 100 that have undergone a special thermal-treatment
can be used as the materials for X-RADAS.
||The mechanical behavior of X-RADAS is essentially
independent of temperature.
||X-RADAS is composed of the pure steel. This
is keeping with the rule of 10.5.5 on the fireproofing
capability and 10.5.8 on the maintenance of
the building code in Taiwan.
||During earthquakes, X-RADAS absorbs earthquake-induced
energy by using the ductile flexural deformation
of the steel plates. In Taiwan, many buildings
equipped with X-RADAS have experienced earthquakes
exceeding 6.5 on the Richter scale. The dampers
in all these buildings performed very well
during the earthquakes.
|The installation, maintenance and inspection
of X-RADAS are easy.
||From the test results of the prototype component
tests and the shaking table tests, it has been
confirmed that X-RADAS is a successful anti-seismic
damper. (94% earthquake-proof efficiency, a
||After the 921 Chi-Chi earthquake, X-RADAS
is the first product to be employed in the
seismic-retrofit engineering in Taiwan.
