Steel pipe RPC frame dense rib composite shear wall

Abstract

The invention provides a steel pipe RPC frame dense rib composite shear wall. Steel pipe RPC frame columns and a dense rib composite plate located between the steel pipe RPC frame columns are included; the steel pipe RPC frame columns and the dense rib composite plate are connected through U-shaped anti-shearing keys, and are poured into a whole with concrete; the dense rib composite plate comprises a plurality of rib beams and rib columns; the reinforced concrete rib beams and the rib columns form a whole rib cell comprising a plurality of rectangular rib cells; each rectangular rib cell is filled with RPC building blocks; and the RPC building blocks, the rib columns and the rib beams are poured into a whole by concrete. According to the steel pipe RPC frame dense rib composite shear wall, the advantages that the steel pipe RPC columns are large in strength and rigidity and good in plasticity and toughness are combined with the advantages that the RPC dense rib composite plate is in energy dissipation and earthquake mitigation, and is adjustable in rigidity, the energy dissipating capacity under the earthquake effect is high, graded energy dissipation can be achieved, and a plurality of seismic fortification lines are formed; and meanwhile, the steel pipe RPC columns and the dense rib composite plate are prefabricated in advance, construction is easy, and maintaining and reinforcing after an earthquake are facilitated.

Description

technical field [0001] The invention belongs to the field of building structures, and in particular relates to a steel pipe RPC frame dense rib composite shear wall. Background technique [0002] With the rapid development of my country's economy, the construction industry is also rising rapidly. With the rapid development of urbanization, the urban population is becoming more and more dense, urban high-rise buildings are constantly developing, and structural systems such as shear walls and frame-shear walls are widely used. In high-rise buildings, especially super high-rise buildings, as the commonly used vertical components and main lateral force-resisting components in high-rise and super high-rise buildings, the deformation capacity and bearing capacity of shear walls are very important. [0003] The seismic capacity of traditional shear walls mainly depends on the ductility of the load-bearing structure, and the energy consumption and seismic capacity is relatively weak....

AI Technical Summary

Problems solved by technology

[0003] The seismic capacity of traditional shear walls mainly depends on the ductility of the load-bearing structure, and the energy consumption and seismic capacity is relatively weak. In addition, most of the shear wall construction techniques in the prior art are cast-in-place. When the shear wall is damaged by an earthquake, it is relatively difficult to repair Difficult to carry out maintenance and reinforcement, thus greatly increasing the post-earthquake reconstruction workload; the improved shear wall that is often used at present is formed by embedding frame columns in the reinforced concrete shear wall to form a framed shear wall. Cross-shaped support is added in the wall plane to form a frame-braced reinforced concrete composite shear wall. The frame-braced reinforced concrete composite shear wall can give full play to the advantages of different materials and make the best use of everything. There are still deficiencies in the type and inner filling masonry materials, and the rigidity and bearing capacity need to be improved
