Reinforced Added Damping and Stiffness (X-RADAS Damper)
01. X-RADAS provides additional stiffness to reduce seismic responses of the lateral displacement, story drift, and torsion of structures during earthquakes.
02. X-RADAS provides maximum energy-dissipation capacity during the peak seismic response of the structure.
03. The periods of the structure can be shifted by using the yielding of X-RADAS to prevent the occurrence of resonance.
04. 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.
05. 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.
06. The mechanical behavior of X-RADAS is essentially independent of temperature.
07. 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.
08. 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.
10. 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 worldwide record)
11. After the 921 Chi-Chi earthquake, X-RADAS is the first product to be employed in the seismic-retrofit engineering in Taiwan.
