Description

Technical Field

[0001] The present application relates to the technical field of building seismic reduction and isolation, and in particular to a cable-type tensile device used in conjunction with a seismic isolation layer. Background Art

[0002] With the development of the global economy and the acceleration of urbanization, high-rise and super-high-rise buildings have appeared frequently. Base isolation is a simple and effective shock absorption technology that has been widely used in various low-rise and medium-rise buildings and has achieved good shock absorption effects. In recent years, this technology has been gradually promoted and applied to high-rise and super-high-rise buildings. Due to the large overturning moment generated by the horizontal seismic force of high-rise and super-high-rise buildings, rubber isolation bearings are prone to tension under strong earthquake motion. Under strong earthquake motion, structures with large aspect ratios will produce obvious bumps and shakes, which will make the tension phenomenon of rubber isolation bearings more obvious. When the rubber isolation bearing is subjected to axial tension, although it does not appear to be damaged much from the appearance, it is easy to form a negative pressure state inside and produce many pores. Studies have shown that after the rubber isolation bearing is subjected to large tensile deformation and then compressed, its vertical compressive stiffness is reduced to about 1 / 2 of the initial stiffness, and when the tensile stress reaches 1.5-3.0MPa, the tensile stiffness of the bearing will drop sharply, showing a bilinear characteristic. The tensile device can improve the vertical tensile resistance of the seismic isolation layer. However, the existing tensile device has the problem of limiting the torsion of the seismic isolation layer, resulting in the torsion being concentrated on the tensile device, and most of the tensile devices have complex structures and high costs.
