Problems solved by technology

The existing problem is: the core part of the oblique hidden support is concrete, and the tensile and compressive capacity is not enough.
The existing problems are: the mechanical performance of the steel plate is weaker than that of other section steel, the tensile and compressive capacity is insufficient, and the support end is prone to local instability
The existing problems are: the connection between the support and the steel beam-column node causes the node to bear a large force, and it is easy to cause the node to be damaged before the component, which does not conform to the seismic design principle of the strong node; when multiple supports are at the same node at the same time, The construction of the nodes is difficult, and it is difficult to guarantee the construction quality

Abstract

This invention relates to a concrete composite shear wall concealed the eccentric supporting steel truss, in addition to a method for making it. Said shear wall allocates two-high mesh reinforcement in the shear wall plate, and adds blind steel shotcrete (10) and bearing bar (17) between the mesh reinforcement, characterized in that: the eccentric supporting steel truss is concealed in the concrete shear wall, and it comprises pattern steel column, pattern steel beam and pattern steel supporting, when the energy dissipating section reach to the yield point in shear, the rest section remains the no yield forced status. The bearing bar is located around the steer shotcrete and anchor fitted go beyond the pattern steel beam; the eccentric supporting steel and steer bearing bar composite the pattern steel concrete blind supporting, whose shape can be X, or the figure eight.

Description

technical field [0001] The invention relates to a concrete composite shear wall with built-in eccentric support steel truss and a manufacturing method thereof, belonging to a composite shear wall and a manufacturing method thereof. Background technique [0002] In recent years, the steel-concrete composite shear wall structure has been widely used in engineering and has been well received by the engineering community. However, the cohesive force between steel and concrete is small, and slip damage is prone to occur, which affects the full play of the overall seismic performance of the structure. How to make concrete medium-section steel fully play its role to improve the comprehensive seismic performance of steel shear walls has become a key technical issue. [0003] Among the existing schemes for improving the seismic performance of steel shear walls, there is the technology of adding hidden reinforcements to reinforced concrete shear walls. The existing problem is: the c...
