A large space self-restoring energy-absorbing structural system

Abstract

The invention discloses a large-space self-recovery energy absorption structure system. The large-space self-recovery energy absorption structure system comprises a lattice shell structure, a latticed tower column, a self-balance hydraulic rod and a hinging structure, wherein the lattice shell structure can be a self-energy-dissipation and self-resetting space lattice shell structure; the upper part of the lattice shell structure is connected with the self-balance hydraulic rod and provides radial force and tensile force for the self-balance hydraulic rod; the lower part of the lattice shell structure is connected with the high-elasticity and high-energy-consumption hinging structure and provides supporting force and tensile force for the hinging structure; the latticed tower column is connected with a foundation and the self-balance hydraulic rod and is used for supporting a structure system. The lattice shell structure, the self-balance hydraulic rod and the hinging structure are deformed under the action of a dynamic load, and then absorb energy transmitted by earthquake waves is absorbed, the energy is transmitted to the foundation through the latticed tower column and the hinging structure, and the structure system realizes self-recovery and energy-absorption and vibration-absorption functions through self-reset after the additional dynamic load is released. On the whole, an energy-absorption and energy-consumption design of the system is carried out, and the good energy-absorption and vibration-absorption effect of the structure system is realized on the basis of reasonable stressing and force transferring.

technical field [0001] The invention relates to the field of building structures in building engineering, in particular to a large-space self-restoring energy-absorbing structure system. Background technique [0002] In the course of the development of human society, a structure that can provide a larger space and span is often the goal that people pursue. The large-space and long-span structure can not only meet the requirements of the large space of the building, but also increase the flexibility of the horizontal separation of the space and the possibility of free adjustment in the vertical direction, and it also has reasonable force, light structure, beautiful shape, and low steel consumption. Low, practical and durable.

Problems solved by technology

In the existing anti-seismic technologies, most of them use to increase the overall rigidity of the building, reinforce the weak links, or use light materials to reduce the weight to achieve the purpose of anti-seismic. Although these technologies have achieved the effect of shock absorption to a certain extent, but The construction cost is greatly increased and there are prone to engineering quality hazards such as brittle failure; in addition, in the earthquake-resistant and shock-absorbing design of large-space building structures, local earthquake-resistant and shock-isolated structures such as shock-resistant damping and shock-isolation bearings are also used. It plays the role of energy absorption and anti-seismic in the horizontal direction of the entire building, but the uneven dynamic load caused by the vibration of the rigid large-space building structure itself cannot be transmitted to the foundation in a timely and uniform manner, resulting in uneven settlement and brittle failure of the building structure and the ground motion is multi-dimensional during an earthquake, and the vibration of the foundation in various directions easily causes the building to generate longitudinal axial force. The anti-seismic / shock-absorbing design of the prior art can only produce compression deformation to realize energy-consuming shock-absorbing / shock-proofing, and cannot Generate rotational deformation to achieve energy absorption and energy consumption; the existing seismic design of large-space building structures is only a partial seismic design, which can achieve local or certain energy consumption and shock absorption / seismic resistance, and the overall seismic effect is not good
