Abstract

The invention discloses a built-in truss combined structure which comprises a combined body. The combined body is composed of steel plates and end columns. A cavity is formed among the end columns and the steel plates. Trusses are arranged in the cavity and fixed to the steel plates in a welded mode. Each truss comprises web members and chord members, wherein the chord members are fixed to the corresponding steel plates in a welded mode. Shear resisting components are arranged on the inner sides of the end columns. Concrete is poured in the cavity. The trusses and the shear resisting components are all arranged in the concrete. According to the built-in truss combined structure, advantages of steel and the concrete are fully achieved, and the structure has an excellent energy-dissipating capacity and a good mechanical property; the trusses are fixed to the steel plates in the welded mode, the steel plates on the two sides are restrained through the trusses, and premature occurrence of local buckling of the steel plates in the construction and use stage is prevented; and meanwhile, the cavity formed by the end columns and the steel plates can serve as a template for concrete pouring, and the construction cost is lowered.

Description

technical field [0001] The invention relates to the technical field of multi-story building structures, in particular to a built-in truss composite structure. Background technique [0002] The usual structural systems of multi-story building structures include frame structure, frame-support structure, frame-shear wall structure, shear wall structure, frame-tube structure, and tube-in-tube structure. In the above structural systems, the frame structure has the lowest building height, in order The height increases progressively, and the tube-in-tube is the highest. [0003] Shear walls are widely used in high-rise buildings because of their superior mechanical properties. In high-rise buildings, they mainly bear horizontal loads and vertical loads (gravity) caused by wind loads or earthquakes. cut) to destroy. Shear walls are divided into plane shear walls and cylindrical shear walls: plane shear walls are used in reinforced concrete frame structures, raised slab structures,...
