Embodiment Construction

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0029] refer to Figure 1 to Figure 5 As shown, a swing self-resetting self-supporting high-rise structure includes a superstructure 1 of a conventional self-supporting high-rise structure section, a cast-in-place foundation 4, a pre-embedded steel plate 6 and a shear ground anchor 7, and the inside of the superstructure 1 is uniform along the inside Multiple sets of cable systems 2 are arranged, and a swing hemisphere 14 and a frictional damping device 3 are arranged between the superstructure 1 and the cast-in-place foundation 4 , and the frictional damping device 3 is arranged around the swinging hemisphere 14 .

[0030] The upper structure 1 includes a cylinder wall 11 and a structural bottom plate 16 arranged at the bottom of the cylinder wall 11. An inner circumferential stiffener 12 is provided at a certain height inside the c...

Abstract

The invention relates to a swing self-reset and self-standing type high-rise structure.The structure mainly comprises an upper portion structure, stay rope systems, a friction damping device, a cast-in-place foundation, a common ground anchor, a pre-buried steel plate and a shearing-resisting ground anchor.The section of the upper portion structure is identical with the section of a common self-standing type high-rise structure while the stay rope systems are evenly distributed along the inner side of the cylinder wall of the upper portion structure, a swing hemisphere is arranged between the upper portion structure and the cast-in-place foundation, and meanwhile the friction damping device is installed at the proper position of the bottom plate.When the structure system bears a large dynamic load, the upper portion structure swings around the contact point of the swing hemisphere and the pre-buried steel plate, energy is dissipated through the friction damping device, shearing force is resisted through the shear-resisting ground anchor, and reset is achieved through prestresss stay ropes after vibration.The swing self-reset and self-standing type high-rise structure has the advantages that the steel using amount of the upper portion structure is small, the structure is simple, cost is low, automatic resetting can be achieved, and maintenance is convenient.

Description

technical field [0001] The invention belongs to the technical field of anti-seismic structural systems of civil engineering, and in particular relates to a swing self-resetting self-supporting high-rise structural system. Background technique [0002] In recent years, with the development of the national economy and the advancement of urbanization, the demand for various self-supporting towering structures (wind turbines, transmission towers, communication towers, chimneys, high pole lights, etc.) . Under the action of earthquake and wind load, this kind of structure will vibrate violently, which seriously affects the normal use and safety performance of the structure. At present, the more commonly used method is to use frequency-tuned dampers to suppress the excessive vibration response of such structures, such as tuned mass dampers (Tuned Mass Damper, TMD), tuned liquid dampers (Tuned Liquid Damper, TMD) and tuned liquid column dampers (Tuned Liquid Column Damper ,TMD). ...
