Abstract

The present invention relates to the technical field of buildings. Disclosed is a partially encased structure frame assembly joint having a restoration function, comprising a partially encased steel-concrete composite upper segment column and lower segment column, and an H-shaped steel beam; a segment type partially encased steel-concrete composite column is provided with stiffening ribs symmetrically arranged on two sides of a web of an H-shaped steel column, and an open section is filled with modular concrete; the upper and lower segment columns are tensionally connected by means of the butt joint of end box type members and after steel strands penetrate through column end stiffening rib bolt holes; the H-shaped steel beam is connected to the columns by means of longitudinal angle iron connectors pre-welded to column flanges; besides, by providing members such as shape memory alloy long bolts at joint junctions, the connection reliability of joints is enhanced, and the energy dissipation and seismic mitigation capabilities of the joints are improved. The present invention can effective exert the performance of both concrete and steel materials, and have both bearing and energy dissipation capacities; moreover, the fully assembled connection can ensure the construction quality, and greatly improves the construction efficiency.

Description

Technical field

[0001] The invention relates to the field of construction technology, and discloses a partially filled structural frame assembly node with a restoration function. Background technique

[0002] Partially encased composite structures (PECS) are filled with concrete within the outsourcing of H-shaped steel and other open section components, and longitudinal reinforcement, stirrups and shear keys are set in the concrete according to performance requirements. The combined structure of other components. Compared with pure steel structure, the addition of concrete improves the structure’s fire resistance, torsional stiffness and other properties, and its bearing capacity and rigidity are further improved; compared with reinforced concrete structures, partially filled steel-concrete composite structures have the same bearing capacity It exhibits better ductility under stress conditions; compared with steel reinforced concrete, this structure has the advantages of higher ...
