The utility model provides a kind of big overhanging rigid-flexible combination space structure system, belong to building construction field.Its technical scheme is: including big overhanging steel structure, internal cable structure and the movable support of the rigid-flexible combination place connecting both, big overhanging steel structure is by outer pipe truss ring beam structure, inner pipe truss ring beam structure, star truss structure and net shell structure constitute, form the whole stiffness very big overhanging main body, internal cable structure is connected with the inner pipe truss ring beam structure of big overhanging steel structure by movable support.The utility model has the beneficial effect that: using rigid structure and flexible structure cooperate, with the coupling stress effect of "rigid-flexible", not only can significantly reduce the seismic response of overall structure, can also improve the wind-induced dynamic response of flexible structure part, simultaneously, big overhanging rigid-flexible combination space structure system effectively improves the structure span capacity, reduces structure deadweight.

The present application relates to a kind of double-column pier system and construction method of quick construction in high-risk seismic area, belong to the technical field of fabricated structure engineering.The double-column pier of construction includes cap beam, pier column, pile cap, pile.The pier column and cap beam are connected by grouting steel pin and slot combination, and the pier column and pile cap are connected by socket and steel pin combination, and the new socket connection node structure of pier column-cap beam / pile cap can better realize mechanical transmission, guarantee the connection reliability and seismic safety of bridge node, the recess of corrugated shape is arranged in the pile cap, and shear stud is arranged below the pier column, which can improve the connection reliability between the pier column and the pile cap, the socket depth of the double-column pier can be reduced to 0.5d by this connection method, and the top grouting method is used to ensure the grouting density.The present application can realize convenient, quick prefabrication and assembly, and has good seismic performance, which guarantees the seismic safety of the system.

The application discloses a metal energy dissipation support, which comprises an outer sleeve connecting end, an inner core rod connecting end and at least one set of energy dissipation modules; the energy dissipation module comprises an outer sleeve and an inner core rod, the inner core rod is provided with a metal energy dissipation plate, the inner wall of the outer sleeve is provided with an energy dissipation limiting component, the inner core rod is arranged in the outer sleeve, and the metal energy dissipation plate on the inner core rod is in limiting cooperation with the energy dissipation limiting component on the inner wall of the outer sleeve; the outer sleeve connecting end is connected with one end of the outer sleeve and forms a certain gap between the inner core rod in the outer sleeve; the inner core rod is connected with the inner core rod in the other end of the outer sleeve and forms a certain gap between the other end of the outer sleeve. The metal energy dissipation support can effectively comprehensively integrate the advantages of traditional metal dampers and buckling restrained braces by adopting the energy dissipation support form and the mode of dissipating seismic energy through metal bending deformation, and is modularized and assembled, so that the practicability is greatly improved.
