Steel tube reinforced concrete composite column-steel beam-lattice steel support shear wall and manufacturing method

Abstract

The invention discloses a steel tube reinforced concrete composite column-steel beam-lattice steel support shear wall and a manufacturing method, and belongs to the field of steel-concrete combined shear walls. The steel tube reinforced concrete composite column-steel beam-lattice steel support shear wall comprises steel tube reinforced concrete composite frame columns, steel tube reinforced concrete composite core columns, steel beams, lattice steel supports and a reinforced concrete shear wall body, wherein the two ends of the shear wall are provided with the steel tube reinforced concrete composite frame columns between which a plurality of parallel steel tube reinforced concrete composite core columns are arranged; the steel tube reinforced concrete composite frame columns are connected with the steel tube reinforced concrete composite core columns by the steel beams and the lattice steel supports and all the steel tube reinforced concrete composite core columns are connected by the steel beams and the lattice steel supports; the shear wall reinforcements are bound; and concrete is cast to construct the steel tube reinforced concrete composite column-steel beam-lattice steel support shear wall. The steel tube reinforced concrete composite column-steel beam-lattice steel support shear wall has the advantages of improved bearing capacity, slow attenuation in bearing capacity and rigidity, stable later anti-seismic performance, improved shear wall ductility and energy consumption performance due to existence of the combined steel structure framework, more superior anti-seismic performance, convenience in steel structure construction and capability of being used in high-rise or large-sized complex multi-storey buildings.

Description

technical field [0001] The invention relates to a "steel tube concrete composite column-steel beam-lattice steel brace" shear wall and a method thereof, which belong to a composite shear wall and a manufacturing method thereof. Background technique [0002] At present, due to the increasing shortage of urban land and the diversification of social needs, the height and span of buildings are increasing, and their shapes are becoming more and more complex. The difficulty of seismic analysis and design of structures is increasing. Many high-rise buildings that have been built or are under construction in our country are located in strong earthquake areas, facing the threat of serious earthquake disasters. The existing reinforced concrete shear walls have poor ductility under earthquake action and are prone to brittle failure, which is very detrimental to the seismic performance of the overall structure. [0003] Shear walls are the core anti-lateral force components in high-ris...
