Tuned Mass Dampers for Earthquake Vibrations of High-rise Buildings using Bee Colony Optimization Technique

This paper investigates the application of Artificial Bee Colony (ABC) method for the optimization of Tuned Mass Dampers (TMDs) employed for high-rise structures including Soil Structure Interaction (SSI). The model is a 40-story building, and Newmark method is utilized for the structure response to Bam earthquake data. The objective is to decrease both maximum displacement and accelerati...

Nonlinear Analysis of Knee-braced Frames under Earthquake Loadings

Nonlinear Analysis of Knee-braced Frames under Earthquake Loadings

Response of high-rise and base-isolated buildings to a hypothetical mw 7.0 blind thrust earthquake.

High-rise flexible-frame buildings are commonly considered to be resistant to shaking from the largest earthquakes. In addition, base isolation has become increasingly popular for critical buildings that should still function after an earthquake. How will these two types of buildings perform if a large earthquake occurs beneath a metropolitan area? To answer this question, we simulated the near...

Assessment of Design Long-period Earthquake Motions for High-rise and Base-isolated Buildings

It was presented in the previous joint panel in 2011 that we have made a proposal on method for evaluating the long-period earthquake motion time history with periods from 0.1 to 10 second using designated earthquake magnitude, shortest distance to the source area and location of hypocenter in view of establishing the generation scheme for design long-period motions for super high-rise building...
