Description

It is a kind of that the system for carrying out structural damping is slid using floor

Technical field

The present invention relates to a kind of system for being slid using floor and carrying out structural damping, belong to building engineering field.

Background technology

Tuned mass damper (Tuned Mass Damper, abbreviation TMD) is a kind of discrete type damping unit, also referred to as Active mass damper or harmonics device, have been widely used for the wind dynamic control of skyscraper, tall and slender structure and bridge.This It is additional certain Substructure System, and by adjusting minor structure parameter on the body construction to plant device, uses up its natural frequency of vibration Measure close to main structure fundamental frequency or excited frequency, when agent structure excited target is vibrated, minor structure will produce one with Structural vibration inertia force effect in opposite direction on the body construction, makes the vibration of agent structure decay and be controlled, prevented The damage and failure of structure.

Generally requiring to add very big quality on main structure body in existing TMD devices (will typically reach body junction More than the 5% of structure quality) considerable damping effect could be produced, this results in many problems.First, hundreds of tons of even upper kilotons Mass be attached in structure, structure can be caused vertically to carry burden and greatly increased;Secondly, to avoid minor structure and body junction The collision that structure relative displacement is excessive and produces, it is necessary to install the damper and stopping means of large-tonnage therebetween, and cost is high, Construction is complicated;Finally, due to which the complexity of additional TMD shock mitigation systems, its construction cost is higher.Therefore, TMD devices more should For the wind-resistant vibration of high-level structure, and the purpose for realizing reduction geological process also has many technical barriers.

The content of the invention

The problem of existing for existing TMD technologies, structural damping is carried out the invention provides a kind of slid using floor System.

The present invention is achieved in that a kind of system for being slid using floor and carrying out structural damping, and the utilization floor is slided The system of shift-in row structural vibration reduction includes:Buffer layer floor, damping by friction layer and elastic buffering mechanism;The damping by friction layer It is laid on the lower section of the buffer layer floor.Appropriate width is left in the same shaft of buffer layer floor, collar tie beam junction, is used for The elastic buffering mechanism is installed.

Further, viscoplasticity energy-consuming shock absorber can be used in the elastic buffering mechanism, and its thickness is with the damping floor Plate is identical, and its rigidity and damping characteristic need to be obtained according to concrete structure calculating analysis.Preventing the buffer layer floor and master Body structure plays a part of dissipative part seismic energy while colliding.

Further, the damping by friction layer choosing is with high coefficient of friction material (coefficient of friction be more than 0.5), to ensure that it can be The buffer layer floor provides enough frictional resistances.The concrete numerical value of coefficient of friction should be analyzed according to concrete structure and determined.

Further, damping by friction layer and buffer layer Vierendeel girder, frame column is whole pour together with.Ensure it in geological process Under do not slide.

Further, the stirrup of the end of buffer layer center pillar and Vierendeel girder needs to be encrypted, to ensure that their rigidity is accorded with Close and require.

Further, the buffer layer floor is slip structure.When building structure is produced under earthquake load load action During vibration, buffer layer floor occurs sliding and produces an inertia force reaction in opposite direction with structural vibration in agent structure On, this inertia force produced by structural vibration is tuned, the vibration to building structure produces tunning effect, makes agent structure Vibration decays and controlled, so that reaching prevents the purpose of structural failure and failure.

Further, analyzed by the optimization to new TMD shock mitigation systems parameter, determine the damping of new TMD shock mitigation systems The set location and number of the important parameters such as coefficient, stiffness coefficient and buffer layer, to realize that assigning skyscraper, Super High builds Build good resistance to shock.

Advantages of the present invention and good effect are:

Buffer layer floor is a part for agent structure, be translated into shock-absorption quality, it is to avoid attached on the body construction Plus excessive quality, and be easier to realize, eliminate and increase because the mass of hundreds of tons of even upper kilotons is attached in structure Big structure vertically carries the possibility of burden;Bottom laying damping by friction layer can provide reliable frictional force for buffer layer floor, apply Work is easy, easily implements;By elastic buffering mechanism reasonable in design, can avoid buffer layer floor in slipping with main body Structure collides;Shock mitigation system simple structure of the present invention, the weight for taking full advantage of structure itself carries out damping, profit Frictional resistance is provided with floor layering, convenient and easy, the relatively existing TMD technologies of its construction cost will be substantially reduced.

Embodiment

In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to Limit the present invention.

The application principle of the present invention is described in detail below in conjunction with the accompanying drawings:

As shown in figure 1, being the system profile provided in an embodiment of the present invention that progress structural damping is slid using floor, subtract Shake layer 4 is arranged in the middle of whole casting layer 5, and the number and particular location that buffer layer 4 is set need to obtain by concrete analysis.

As shown in Fig. 2 the system provided in an embodiment of the present invention for sliding progress structural damping using floor includes:Buffer layer Floor 1, damping by friction layer 2 and elastic buffer zone 3;The damping by friction layer 2 is laid on the lower section of the buffer layer floor 1;Institute State the same shaft of buffer layer floor 1, Vierendeel girder junction and leave appropriate width, the elastic buffering mechanism 3 is turned for pacifying.

The buffer layer floor 1 is slip structure.

Damping by friction layer 2 selects high coefficient of friction material, the Vierendeel girder, frame column with buffer layer are whole pour together with.

The thickness of the elastic buffering mechanism 3 is identical with the buffer layer floor 1.

The application principle of the present invention is further described with reference to specific embodiment;

It is provided in an embodiment of the present invention to be slid using floor in the system for carrying out structural damping, by setting damping by friction layer 2 and elastic buffer zone, together constitute a kind of new TMD shock mitigation systems with buffer layer floor 1.Wherein, buffer layer floor 1 is This new TMD shock mitigation systems provide quality, and damping by friction layer 2 provides damping for it, the offer rigidity of elastic buffering mechanism 3 with Part is damped.

Wherein viscoplasticity energy-consuming shock absorber can be used in elastic buffering mechanism 3, and its thickness is with the phase of buffer layer floor 1 Together, its rigidity and damping characteristic need to be obtained according to concrete structure calculating analysis.Sent out preventing buffer layer floor with agent structure Play a part of dissipative part seismic energy while raw collision.

Damping by friction layer 2 is from high coefficient of friction material (coefficient of friction is more than 0.5), to ensure that it can be for buffer layer floor Enough frictional resistances are provided, the concrete numerical value of coefficient of friction should be analyzed according to concrete structure to be determined.And by damping by friction layer 2 with With layer Vierendeel girder, frame column is whole pours together.Ensure that it does not slide under geological process.
