Prefabricated steel-reinforced concrete combined special-shaped energy-dissipating column
A prefabricated steel-reinforced concrete combined special-shaped energy-dissipating column is structurally characterized by comprising a steel reinforced concrete main column, a steel reinforced concrete auxiliary column and a steel-structural energy-dissipating link beam. The auxiliary beam is wrapped in a wall. The energy-dissipating link beam is connected separately with profile steel in the main column and the auxiliary column by welding under equal strength, thus a steel keel having dumbbell shaped section is formed for the prefabricated steel-reinforced concrete combined special-shaped energy-dissipating column. Vertical bars and stirrups are erected on the steel keel, the vertical bars, the stirrups and the steel keel form an internal steel framework, and concrete is poured outside the framework. The column is applied to a fabricated steel-reinforced concrete structure construction, the energy dissipation and seismic reduction principle is applied to the combined special-shaped column, the feature of the combined column being high in ductility and the feature of a coupled shear wall link beam yielding to dissipate energy are combined, and great bending rigidity is obtained with small sectional area. Parts are prefabricated in factories and connected in situ through bolts, construction speed is high, and precision is high.
