Abstract
The invention discloses a frame system comprising a prefabricated steel tube concrete combined special-shaped column and an energy-consuming steel plate wall. The system mainly comprises prefabricatedcorner columns, prefabricated side columns and prefabricated middle columns, H-shaped steel beams, the energy-consuming steel plate wall with elliptical holes, prefabricated steel floors, column-column connection flanges, column-column connection rubber pads, column-beam connection parts, middle column-beam connection part, column-wall connection parts and the like, wherein the prefabricated corner columns, prefabricated side columns and prefabricated middle columns are made of circular steel tube concrete columns and steel batten plates; the column-column connection flanges, the column-beamconnection parts, the middle column-beam connection parts and the column-wall connection parts are welded and prefabricated with steel pipes; the structural parts are connected by high-strength bolts.A rubber pad is placed between the upper and lower columns to connect the flanges to enhance the connection. Energy-consuming steel wall and steel slabs open holes to improve the energy consumption and seismic performance of the structural system. The invention realizes full dry construction, no wet operation, simple and quick construction engineering, high construction efficiency, stable and reliable node connection, and good seismic performance of the structural system.
Description
technical field [0001] The invention relates to a frame system including fabricated steel pipe concrete combined special-shaped columns and energy-dissipating steel plate walls, mainly including steel pipe concrete composite special-shaped columns, steel beams, steel floors and energy-consuming steel plate walls, and belongs to the field of new building structure technology and structural earthquake resistance and shock absorption . Background technique [0002] Special-shaped column refers to a column whose cross-sectional geometry is L-shaped, T-shaped, cross-shaped or straight, and the ratio of limb height to limb thickness of each limb of the cross-section is not greater than 4. The special-shaped column structure is evolved from the frame-shear wall structure. It is composed of special-shaped columns, beams, floors, and walls. The thickness of the column limbs is the same as the width of the beams and the thickness of the walls. With the advantage of not exposing the co...
