Description
Technical Field
The utility model relates to a building structure supports the field, concretely relates to crooked power consumption type cable system supports.
Background
The lateral rigidity and the shock resistance of the frame structure can be effectively improved through the support. The ordinary support is easy to generate buckling damage under the action of an earthquake, the difficulty of repair and reinforcement engineering after the damage is high, and the problem of support buckling is solved due to the appearance of the cable system support, but in the traditional cable system support, as shown in fig. 1-2, under a large vibration amplitude, only one steel cable provides lateral stiffness in a tensioned state, the other steel cable in a relaxed state does not contribute to the lateral force resistance of the structure, the steel cable is subjected to brittle failure under the lateral force due to the low ductility of the tensioned steel cable, the risk of structural collapse is increased, and the steel cable with low ductility contributes little or hardly contributes to the energy consumption capability of the lifting structure. Therefore, if the deformation tendencies of the two steel cables can be utilized simultaneously and the energy consumption measures are combined to consume energy, the support and the frame structure can be further prevented from being damaged.
The existing energy consumption measures are mainly characterized in that the energy consumption capacity of the structure is enhanced through metal or different types of dampers, the energy consumption measures can be mainly divided into axial yielding energy consumption, shearing yielding energy consumption and bending yielding energy consumption according to different energy consumption mechanisms, the existing energy consumption measures for bending yielding are mainly applied to the field of dampers, the research on the synergistic energy consumption of the dampers and supports is still lacked at present, and the excellent visual damage characteristic after yielding has great potential in the aspect of reinforcing and repairing the building structure.
The traditional cable system support is also provided with a hollow steel cylinder in the center, so that the steel cable can penetrate through the hollow steel cylinder at a larger gradient, and the steel cable at two sides can keep tension under the action of lateral force through the rotation limitation of the hollow steel cylinder. Tests show that the cable system support with the central steel cylinder can greatly reduce the increase of column pressure caused by the action of common support, and limit the interlayer displacement within a certain range, but the added hollow steel cylinder does not bring enough energy consumption capability to the structure, and cannot dissipate seismic energy under the action of earthquake.
In 2018, Babak proposes that a steel plate is additionally arranged at the support center of a cable system, and a steel cable is always in a tension state through the rotation of a middle steel plate under the action of lateral force, so that the lateral rigidity of the structure is improved.
In 2019, M.H.Mehrabi proposes that steel cables are connected together at intersection points by a pre-pressing spring in a traditional cable system supporting center, under the action of the pre-pressing spring force, when each steel cable is in a tension state, and a frame structure generates lateral displacement, the pre-pressing spring extends to delay the action of the steel cable, when the frame returns to the original position, the spring is compressed again, the system has stronger self-recovery capability through the spring, but the spring does not allow the shaping deformation, and the energy consumption capability under the elastic deformation is limited. After a single lateral force action, the self-recovery property of the spring still drives the structure to oscillate for a small period, and the oscillation is unfavorable for preventing resonance; under the action of strong earthquake, only one spring is utilized to prevent the system from responding more, the energy consumption capability is limited, if the spring enters a plastic deformation state, the difference between the system and the traditional cable system support is the same, and the performance of the system is directly determined by the performance of the spring. Additionally, bracing of the rigging with a center pre-stressed spring requires the spring to be completely horizontal, otherwise the stress of only one side of the spring is amplified and the overall balance is disturbed. And the steel cable has certain deflection angle requirement through the spring, which undoubtedly brings great difficulty to construction and needs high technical level installation. In addition, the degree of preload of the spring is difficult to grasp during construction.
