The　parameter　of　a　kind　of　viscous　damper　is　obtained　through　pseudo-dynamic　test,　and　the　passive　control　shaking　table　experiment　of　a　double-layer　reticulated　shell　with　some　bottom　chords　replaced　by　the　dampers　are　carried　out,　in　which　several　earthquake　ground　motions　of　different　magnitudes　are　input.　The　result　indicates　that　the　vibration　of　the　shell　with　dampers　is　obviously　reduced　compared　with　that　without　dampers.　And　the　comparison　of　the　experimental　result　and　the　theoretical　simulation　is　made,　from　which　good　consistence　is　shown;　earthquake　reduction　factor.
