Connecting mode of self-resetting energy-dissipation coupled shear wall with super-strong deformation capacity
The invention discloses a connecting mode of a self-resetting energy-consuming coupled shear wall with super-strong deformability, which structurally comprises two shear walls and a connecting unit, the left connecting beam and the right connecting beam are connected with the shear wall through bolts respectively, the elastic reset assembly and the left connecting beam and the right connecting beam are concentrically arranged, the two outer end plates enable the left connecting beam, the right connecting beam and the elastic reset assembly to form a whole, and the friction energy dissipation assembly is assembled on the side faces of the left connecting beam and the right connecting beam through bolts. A T-shaped steel flange in the coupling beam is connected with a threaded sleeve pre-buried in a shear wall through a bolt, an elastic reset assembly is arranged in the sleeve, the self-reset function is achieved through elastic potential energy stored by the elastic reset assembly, and the elastic reset assembly is formed by connecting disc springs and pre-stressed tendon sets connected in series in series. And the ductility of the structure is greatly improved. A hole is formed in the middle of the outer sleeve to place the movable plate, a strip-shaped hole is formed in the middle of the inner sleeve, the movable plate and the inner sleeve are pressed through the pre-tightening bolt, and sliding friction between the movable plate and the inner sleeve can be caused by the mutual dislocation mechanism of the left connecting beam and the right connecting beam, so that the friction energy dissipation effect is achieved, and damage to components can be effectively reduced or avoided; the energy consumption function and the recoverable function of the coupled shear wall are achieved, and the anti-seismic requirements of different levels can be met.
