RADAS Device Technology for Retrofitting Damaged Structures in 921 Chi-Chi Earthquake
View through CrossRef
The 921 Chi-Chi earthquake was the most destructive earthquake for Taiwan in the twentieth century. The earthquake caused severe damage or collapse to residential and public structures. In addition to the use of traditional earthquake-resistant technologies for retrofitting damaged structures, new structural control technologies have been also adopted. The RADAS (Reinforced Added Damping and Stiffness) device is a new type of earthquake-proof technology. The RADAS device has been proved as a very reliable energy-absorbing device for seismic hazard mitigation through shaking table tests. In this paper, we will present the application of RADAS devices to damaged structures in the 921 Chi-Chi earthquake. It is also illustrated in this study that new structures equipped with RADAS Devices can enhance seismic resistibility, even if earthquakes exceed ML 7.3 magnitude on the Richter scale. Therefore, it is a sensible choice to use RADAS devices to retrofit damaged structures and to enhance the earthquake-resistant capacity of new structures.
