Oblique steel support concrete shear wall composite coupling beams and production method thereof

Abstract

The invention relates to a combined connecting beam of an oblique steel supported concrete shear wall and a manufacturing method thereof, and belongs to a connecting beam of a shear wall. The connecting beam comprises a horizontal steel bar, a connecting beam hoop bound outside the horizontal steel bar, two oblique steel bar supports arranged in an X shape and oblique steel supports arranged inside the oblique steel bar supports. Two ends of the oblique steel supports extend into the concrete shear wall bodies at two sides of the connecting beam. The upper part and the lower part of the connecting beam are provided with frame beams, and the frame beams, the oblique steel supports and the oblique steel bar supports are combined to form the combined connecting beam of the oblique steel supported concrete shear wall. The axial force in the coupling wall is reduced, and the ductility of the connecting beam is increased. The oblique steel supports and the oblique steel bar supports crosseddiagonally are comparatively evenly distributed at the height of the connecting beam along a main tensile stress direction, and can resist the oblique main tensile stress better, wherein the diagonaloblique bars can more remarkably improve shear rigidity of members and reduce shear deformation; and in the action direction of the main compressive stress, the oblique steel supports and the obliquesteel bar supports also assist the concrete to bear the main compressive stress.

Description

technical field [0001] The invention relates to a composite connecting beam of a concrete shear wall supported by inclined steel and a manufacturing method thereof, belonging to a connecting beam of a shear wall. Background technique [0002] Beams connected to shear walls are called coupling beams. Coupling beams generally have a relatively small span height, and the shear walls connected to them have high stiffness. Therefore, under the action of horizontal forces in high-rise buildings, the internal force of the coupling beams is often large, and the section design often exceeds the limit. In the design, it is always necessary to take appropriate measures to adjust the internal force of the coupling beam, so that the structure can not only bear the vertical load capacity, but also meet the strength and stiffness requirements under the horizontal force. [0003] Under the action of wind load and earthquake load, the shear wall pier produces bending deformation, which make...

Problems solved by technology

Generally, under the action of wind load and earthquake load, the internal force of the coupling beam is often very large, so that the coupling beam is over-reinforced or over-limited.
