SEISMIC RESISTIBILITY OF HIGH-RISE BUILDINGS WITHCOMBINED VELOCITY-DEPENDENT AND VELOCITY-INDEPENDENT DEVICES

摘要

The use of supplemental damping to dissipate the seismic energy is considered to be one of the most economic and effective ways to mitigate the effects of earthquakes on buildings. Both the tapered-plate energy absorber (TPEA) and viscoelastic (VE) damper are promising devices for dissipating energy. Velocity-independent devices such as TPEA devices may not provide any damping to the structure during minor earthquakes. In addition, velocity-dependent devices such as VE dampers fail to reduce structural response at the early stage (very first few seconds) of earthquakes. The adoption of combined Velocity-dependent and velocity-independent devices for the 10-story building frame show that the shortcomings of individual Dampers can be minimized, and the most economical way could be achieved by this method.
