Description

Technical Field

[0001] The utility model relates to the technical field of building seismic isolation, and in particular to a double-order tensile friction pendulum support. Background Art

[0002] Isolation and tensile resistance are particularly important for the safety of buildings. Tensile friction pendulum is a commonly used seismic isolation technology in buildings. The tensile friction pendulum achieves smaller horizontal stiffness and larger horizontal deformation capacity through the mutual sliding of the spherical or cylindrical sliding friction surfaces on the support plate and the spherical crown, thereby reducing the dynamic response caused by horizontal earthquakes in the upper structure; the tensile force is transmitted through the guide hooks on the support plate and the spherical crown to achieve reliable vertical tensile resistance and reduce the dynamic response of the upper structure caused by earthquakes in the vertical direction. The existing tensile friction pendulum support, for example, has a small deformation, Only lateral or longitudinal tensile slippage can be achieved. For example, the utility model patent disclosed as CN213234452U records a building tensile friction pendulum bearing, including an upper bearing plate and a lower bearing plate, wherein the upper bearing plate is located above the lower bearing plate, and a spherical crown lining is arranged between the upper bearing plate and the lower bearing plate. In this disclosed patent, the spherical crown lining can only achieve lateral tensile slippage, but it is difficult to achieve tensile slippage in any direction. When the building is subjected to tension in other directions, the slippage cannot be adjusted, thereby reducing the reliability performance of the tensile friction pendulum bearing.
