Abstract
The invention discloses a built-in and multi-cavity double steel plate and concrete filled steel tubular column combined shearing wall and a manufacturing method, and relates to the field of the construction technology. According to the built-in and multi-cavity double steel plate and concrete filled steel tubular column combined shearing wall, cast-in-place reinforced concrete, a steel plate shearing wall and a concrete filled steel tube are combined into the combined shearing wall. A plurality of transverse steel plates are arranged between the double steel plates to form a multi-cavity structure between the double steel plates. Bar-mat reinforcements formed by transversal distributed bars and longitudinal distributed bars arranged on the two sides of the combined multi-cavity steel plates are connected through stretching bars. Compared with an existing shearing wall, the built-in and multi-cavity double steel plate and concrete filled steel tubular column combined shearing wall has the advantages of being large in initial rigidity, high in bearing capacity, slow in bearing and rigidity attenuation, good in overall anti-seismic and energy consumption performance and relatively stable in later anti-seismic property of the wall.
