Described buckling-restrained member adopts the confining part of cast mortar formation in concrete filled steel tubular member or all steel system member or reinforced concrete member or the steel pipe or the confining part that the interior cast of steel pipe steel fibrous concrete forms.
Described non-cohesive material can be that epoxy resin or asphalt varniss or ethene basic unit add foam or rubber layer or silicone rubber layers or silicones and add epoxy resin or polyethylene sheeting or butyl rubber.
Described core primary structure member can be fixed on the end plate by bolt connection or the mode that is welded to connect.
Can weld stiffening rib on the described end plate, make end plate form the rigid body that rigidity is very big, end plate should be out of shape very for a short time when stressed, and distortion is mainly concentrated on the core primary structure member.
Should be welded to connect part on the described end plate, novel tension and compression energy-consumption damper and structure are connected and fixed by connector.
Described buckling-restrained member can not produce prior to the core primary structure member and destroy.
The utlity model has following remarkable advantage:
(1) rigidity that provides to structure is bigger.Owing to utilize the tension and compression deformation of core primary structure member to realize power consumption, when realizing power consumption, can provide bigger rigidity to structure.
(2) power consumption is effective.Because the lateral deformation of core primary structure member is subjected to the restriction of buckling-restrained member, so the overwhelming majority of core primary structure member is deformed into axial deformation, thereby can dissipate a large amount of seismic energies when avoiding flexing.
The utility model can be used in the various building structure, such as frame construction, and the frame-shear wall structure, in the large-span structure, can not only provide enough rigidity to structure, and a large amount of seismic energies that can dissipate, will be widely used in all kinds of building construction vibration controls field.
