C-shaped thin-shell interlayer earthquake isolation device with threshold-value-buckling-unloading self-resetting function and system

Abstract

The invention discloses a C-shaped thin-shell interlayer earthquake isolation device with the threshold-value-buckling-unloading self-resetting function. The C-shaped thin-shell interlayer earthquake isolation device comprises an upper steel plate, a lower steel plate and C-shaped-opening cylindrical shells connected between the upper steel plate and the lower steel plate; the mode of the C-shaped-opening cylindrical shells can be the array mode / annular mode. The C-shaped thin-shell interlayer earthquake isolation device has the quite-large vertical bearing capacity and the rigidity, and can effectively support the weight of buildings; as the C-shaped-opening cylindrical shell structures can have large-deformation elastic displacement in the horizontal direction, by means of the structural system that the C-shaped thin-shell interlayer earthquake isolation device is matched with a damping system and a supporting protection system, earthquake energy can be effectively isolated, it is avoided that the earthquake energy is transmitted to the upper-portion structure, earthquake responses of the buildings are reduced, and the body structures of the buildings are not damaged or not collapsed under the effect of a strong earthquake; as elastic strain energy can be gathered when the C-shaped-opening cylindrical shell structures are largely deformed, the C-shaped thin-shell interlayer earthquake isolation device has the good self-resetting function in the earthquake, the bearing function of the earthquake isolation device can be completely recovered through a hydraulic jack after the earthquake, and the large-earthquake-repairing sustainable-development engineering earthquake isolation aim is achieved.

Description

technical field [0001] The invention belongs to the technical field of shockproof and shock absorption of building structures, and in particular relates to a C-type thin shell shock-isolation device and system with threshold buckling unloading and self-resetting functions. Background technique [0002] Recoverable functional structure is a new type of shock-absorbing control structure. It can not only protect people's lives and property during earthquakes, but also help people return to normal life as soon as possible after a major earthquake. It is an ideal new structure for seismic design. direction. The anti-seismic thinking in my country at the present stage is "not damaged by small earthquakes, repairable by moderate earthquakes, and not collapsed by major earthquakes". However, due to the uncertainty and complexity of earthquakes, the structure may suffer from an earthquake with a greater intensity than the seismic fortification, resulting in serious damage to structu...

Problems solved by technology

However, due to the uncertainty and complexity of the earthquake, the structure may suffer from an earthquake with a greater intensity than the seismic fortification, resulting in serious damage to the structural components.

In addition, although the structure did not collapse after being subjected to an earthquake of fortification intensity, some components were difficult to reinforce and repair due to the particularity of the damaged location and the severity of the damage. In the end, the entire structure had to be demolished and rebuilt, resulting in huge waste and affecting people's normal life
