Passive　control　technology　is　an　effective　method　for　earthquake　disaster　prevention　of　structures.　It　absorbs　and　dissipates　vibration　energy　of　structures　by　using　control　devices,　which　is　quite　different　from　traditional　ways　of　strengthening　the　structural　resistance　by　its　own　strength　and　stiffness.　In　this　paper,　present　situation　on　application　of　the　passive　control　technology　in　long-span　spatial　structures　is　summarized　according　to　seismic　isolation,　energy　dissipation　and　tuned　vibration　reduction,　respectively.　The　related　control　measures　and　control　performance　are　also　introduced.　Practical　conclusions　are　made.　The　information　given　in　this　paper　will　provide　good　references　for　practical　design　of　the　long-span　spatial　structures　and　further　promotes　the　development　of　control　technology　in　the　structures.
