In　order　to　clarify　influences　of　connected　rigidity　on　damping　effects　of　tuned　particle　dampers　(TPDs)　and　determine　the　available　optimal　range　of　the　connected　rigidity　between　TPD　and　a　structure,　a　1/30-scale　RC　frame　model　was　designed　and　manufactured,　TPDs　with　various　connected　rigidities　were　designed　to　reduce　vibrations　of　the　test　model,　influences　of　connected　rigidity　on　TPD＇s　vibration　control　effect　was　analyzed　through　a　series　of　shaking　table　tests.　The　results　showed　that　the　TPDs　properly　designed　can　reduce　structural　displacement　responses　effectively;　the　connected　rigidity　between　TPD　and　the　controlled　structure　has　obvious　influences　on　the　TPD　vibration　control　effect;　when　the　ratio　of　the　TPD＇s　natural　frequency　to　the　structure＇s　fundamental　frequency　in　the　controlled　direction　is　within　a　range　of　0.90　to　1.10,　the　TPD＇s　vibration　control　effect　is　better.　©　2018,　Editorial　Office　of　Journal　of　Vibration　and　Shock.　All　right　reserved.
