T he motion equation o connected mult-i structure vibr at ion control system is established , w hile t he connection structur e is r eg ar ded as an attached mass . A ast CQ C algor ithm is applied to calculate the P SD matrices o r andom responses o co nnected mult-i structur e system w ith non- orthog onal damping matrix under eart hquake excitation . T he examples show the e ectiveness o the co ntrol system . T he in luence actors o control system are investigated. F inal- ly , opt imization or parameter o the control system is discussed.
