摘要: 
This paper deals with the optimal design of passive tuned mass dampers
(PTMDs) to reduce the dynamic responses of torsionally-coupled buildings under
bi-lateral earthquake excitations. Some practical design issues such as the
optimal installed locations and moving direction of PTMDs are considered. The
optimal PTMD's system parameters are determined by minimizing the meansquare
displacement response ratio of the controlled DOF between the building with and
without PTMDs. In addition, the parametric studies about the PTMD's planar
position and effect of detuning are investigated to realize their influence on
the response control efficacy. In order to reduce the structural responses when
a building subjected to bi-lateral earthquakes, the necessity of a second PTMD
and its optimum design are also studied. Performance of the proposed optimal
PTMDs is demonstrated by numerical studies of the seismic behavior of an
one-story square torsionally-coupled building with different static
eccentricities.
