Abstract
The invention discloses a built-in section steel column-lattice steel beam-mesh steel support concrete wall body and a manufacturing method, and belongs to the field of steel-concrete combined shear walls. The wall body comprises section steel laminated border columns, section steel core columns, lattice steel beams, mesh steel supports and a reinforced concrete shear wall body. The section steel laminated border columns are arranged at the two ends of the shear wall body. The section steel core columns are arranged in parallel between the section steel laminated border columns. The section steel laminated border columns are connected with the section steel core columns through the lattice steel beams and the mesh steel supports, and the section steel core columns are connected with one another through the lattice steel beams and the mesh steel supports. Reinforcements of the shear wall body are assembled, and concrete is poured to form the built-in section steel column-lattice steel beam-mesh steel support concrete wall body. Compared with an ordinary concrete-filled steel tube border shear wall and an ordinary steel plate shear wall, the built-in section steel column-lattice steel beam-mesh steel support concrete wall body has the advantages that the bearing capability is improved, the bearing capability and the rigidity are slowly attenuated, and the post seismic performance is stable; by a section steel column-lattice steel beam-mesh steel support steel structure skeleton, the ductility and energy consumption performance of the shear wall are greatly improved, and the seismic performance is high; and a steel structure is convenient to construct, and can be used for the seismic design of a large-sized complex high-rise buildings.
Description
technical field [0001] The invention relates to a built-in steel column-lattice steel beam-reticular steel braced concrete wall and its method, and belongs to a new type of steel-concrete composite shear wall that consumes earthquake input structural energy and improves the anti-seismic performance of the structure and its manufacture method. Background technique [0002] The shear wall structure can effectively reduce the lateral displacement due to its high stiffness against lateral displacement and has certain ductility, so it has gradually become a system widely used in modern high-rise buildings. The shear wall has high rigidity and high strength, which can effectively reduce lateral movement, and generally can well meet the seismic requirements under frequent earthquakes. However, in the case of a large earthquake, due to the large peak value of seismic acceleration and the large input seismic energy, the shear wall is required to have better energy dissipation capaci...
