Abstract

The invention relates to an interconnected space shear wall, in particular to a concrete filled steel tube laminated column frame inbuilt steel plate and the steel truss interconnected space shear wall, which is composed of a concrete filled steel tube laminated column frame, a shear wallboard and a connecting beam, wherein, two sides of the shear wallboard are provided with the concrete filled steel tube laminated column frames, and the steel plate is arranged in the reinforced concrete shear wallboard of the shear wall; two outer sides of the steel plate are provided with a reinforcing mattress composed of reinforcing steel transversely distributed and reinforcing steel bars longitudinally distributed; concrete-filled steel tube columns are arranged in the concrete filled steel tube laminated column frame; the steel plate and the reinforcing steel bars transversely distributed are respectively welded with the concrete-filled steel tube columns at two sides; the connecting beam position is provided with two X-shaped diagonal steel trusses; the upper part and the lower part of the connecting beam are provided with truss girders; and the diagonal steel trusses, the truss girders and the steel plates are welded together at an angular point. The interconnected space shear wall of the invention has the characteristics of large initial rigid, high loading capability, slowed bearing capacity and rigidity attenuation, more anti-seismic defensive lines, favourable overall anti-seismic energy consumption performance, relatively stable anti-seismic performance in a later period and the like.

Description

technical field [0001] The invention relates to a combined shear wall, in particular to a steel truss combined shear wall with built-in steel plates and steel truss composite column frames on both sides. Background technique [0002] Shear walls and the tubes composed of shear walls are the core anti-lateral force components of high-rise buildings, so the development of shear walls with good seismic performance is one of the key technologies for building anti-seismic design. The use of CFST frame can effectively combine the advantages of large lateral stiffness of the shear wall and good seismic performance of CFST, effectively improving the seismic bearing capacity, ductility and energy dissipation capacity of the shear wall. However, the CFST frame also has the disadvantages of poor corrosion resistance and fire resistance. [0003] In the cooperative work of wall piers and coupling beams, the shear wall should have sufficient rigidity and strength. Under normal service ...
