Seismic response of subsystems in irregular buildings

subsystems multi-connected to primary structures with irregularities. The proposed approach is
more accurate than the cascade approximation, often used in the design practice, as the primarysecondary
dynamic interaction is considered through the modes of vibration of the two components.
The results of parametric analyses on a representative case study reveal similar trends in the displacements
of the two components for mass irregularities in elevation, while sti ness irregularities
in plan can result in significant torsional motion in both components, with the effects in terms of
absolute accelerations being in general larger than those associated with the lateral drifts. This suggests
that dynamic analyses with the component-mode synthesis method are particularly indicated
for the seismic assessment of acceleration-sensitive secondary subsystems.
