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.

Description

technical field [0001] The invention relates to a double-steel steel composite shear wall with a frame of a steel pipe concrete column, in particular to a composite shear wall with a built-in multi-cavity double steel plate and a steel pipe concrete column and a method thereof. Background technique [0002] With the development of my country's national economy and the continuous expansion of the scale of infrastructure construction, especially the structural forms with super high and large spans and other special requirements are becoming more and more common, and higher requirements are put forward for the structure, while new materials and new technologies are constantly emerging. Conditions were created to meet these requirements. The steel-concrete composite structure makes full use of the respective material properties of steel and concrete, and has the advantages of high bearing capacity, high rigidity, good seismic performance and dynamic performance, small component c...
