In this paper, the performance of semi-active viscous dampers in reducing the response
of tall buildings to earthquake acceleration is optimized using genetic algorithms. Torsional effects due
to irregularities exist in the building and due to unsymmetrical placement of the dampers are taken into
account through 3-D modeling of the building. For the numerical example, a twelve-story building is
chosen. The building is modeled as a 3-D frame. The equations of motion of the building with semi-active
viscous dampers, subjected to earthquake acceleration, is written, resolved in state space and the results
are compared with those of the uncontrolled building. Moreover, in order to minimize building responses
such as top story displacement and base shear, the required number and location of dampers are optimized
using genetic algorithms.
