Description
Technical field
The utility model belongs to energy-dissipating and shock-absorbing field, relates to a kind of steel work damping wall, is specifically related to a kind of damping wall with semi-active control function.
Background technology
Energy-dissipating and shock-absorbing technology refers to and adds energy dissipator or energy dissipation component in certain position of building structure, in practice on concrete wall of being everlasting, node, between adjacent structure, between main body accessory structure, floor space equipotential installs and put.
Energy dissipation component is jointly made up of supporting member and damping device one, and energy-consuming shock absorber namely installs the structure of energy-consuming parts.Seismic energy dissipation structure is in elastic state completely under little shake effect, and energy-consuming parts is supplied to the rigidity of agent structure abundance, ensures that it normally uses.Large earthquake centre, first energy dissipator starts working, and damping increases instantaneously, and weaken rapidly the acceleration of structure, speed and displacement etc., energy dissipator, always prior to main structure body generation plastic strain, ensure that the security performance of main structure body; Most seismic energies of input structure are consumed, and by power consumption damping unit, the distortion of bending and twisting elastoplasticity hysteresis occurs or utilizes its frictional force to dissipate the energy of Seismic input structure, finally reach the object reducing agent structure earthquake response.
Energy-dissipating and shock-absorbing technology has multiple advantage, and make other reinforcing techniques too far behind to catch up: (1) adds damper in the structure, structural body components does not participate in power consumption process, and whole process is all in operator guards main body, makes it escape death by sheer luck, safe and reliable; (2) draw materials conveniently, construct very clear, save material, saving construction cost, economic benefit is obvious; (3) construction is simple, and the duration is short, and it is convenient to install; (4) can dissipate after installing seismic energy effectively, and significantly reduce earthquake sheet, consolidation effect is obvious.
The energy-consumption shock-absorption device kind developed is a lot, is summed up and is mainly divided into following a few class: steel energy consumer, friction energy dissipation device, viscoelastic damper and Effects of Viscous Fluid Damper etc.
Current damping wall construction adopts steel energy consumer, friction energy dissipation device and Effects of Viscous Fluid Damper substantially.Steel energy consumer utilizes steel after entering plastic range, have good hysteretic characteristic absorption energy, but its power consumption steel life cycle is short, and performance capable of circulation is low, and hysteresis loop easily occurs sliding phenomenon.Same, for friction energy dissipation device, along with the increase of cycle-index, the wearing and tearing of rubbing surface can make the frictional force of friction energy dissipation device on a declining curve; Meanwhile, high-strength bolt and friction element and Kong Cao's size etc. also can produce harmful effect to friction energy dissipation device.As for viscous damper, its use and maintenance cost is all higher, and lacks corresponding design specifications and damper control of acceptance.
Above-mentioned energy-consumption shock-absorption device is passive energy-consuming shock absorber, does not have the ACTIVE CONTROL performance to vibrations, is difficult to realize intelligentized control method.There is structure and complicated construction technique simultaneously, be unfavorable for rapid construction reduction of erection time and the problem such as less economical.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of semi-active control damping wall based on ER effect (ER) damping, and have reaction speed and soon, easily realize computer and control, anti-seismic performance is superior, can the feature such as green construction fast.
The technical solution adopted in the utility model is:
A kind of semi-active control damping wall based on er damping, it comprises steel frame and electro-rheological fluid damper, the guide rod being passed through self two ends between two side framed columns in steel frame by four electro-rheological fluid dampers is that " X " shape connects with being connected force disk, and electro-rheological fluid damper carries out signal by holding wire or wireless data signal transmitter with monitor control system and is connected.
Further: four electro-rheological fluid dampers are symmetrical set, wherein: two electro-rheological fluid dampers being positioned at top are connected with the frame column on both sides by the guide rod of self, two electro-rheological fluid dampers being positioned at below carry out grounding connection by the guide rod of self.
Further: the external junction of guide rod all adopts articulated manner to connect.
The utility model has following features: (1) structure is simple, and Path of Force Transfer is clear, can construct with efficient by quick assembling; (2) can be made adjustment and control to er damping by monitor control system (computer control system), realize the semi-active control to vibrations; (3) cost is low, is easy to safeguard.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral: steel frame 1, electro-rheological fluid damper 2, guide rod 3, connects force disk 4, wireless data signal transmitter 5, monitor control system 6.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further, but scope of the present utility model is not limited to following embodiment.
A kind of semi-active control damping wall based on er damping, it comprises steel frame 1 and electro-rheological fluid damper 2, the guide rod 3 being passed through self two ends between two side framed columns in steel frame 1 by four electro-rheological fluid dampers 2 is that " X " shape connects with being connected force disk 4, namely connected with four connecting holes be connected on force disk 4 by the guide rod 3 of four electro-rheological fluid damper one end simultaneously, four electro-rheological fluid dampers 2 scatter to four direction in " X " shape, and electro-rheological fluid damper 2 carries out signal by holding wire or wireless data signal transmitter 5 with monitor control system 6 and is connected.
Four electro-rheological fluid dampers 2 are symmetrical set, and wherein: two electro-rheological fluid dampers 2 being positioned at top are connected with the frame column on both sides by the guide rod 3 of self, two electro-rheological fluid dampers 2 being positioned at below carry out grounding connection by the guide rod 3 of self.
Guide rod 3 be connected force disk 4, frame column and ground connection, all adopt articulated manner connect.
When structure produces relative floor displacement by shock effect, two cornerwise length have the trend elongated or shortened accordingly, and the electro-rheological fluid damper 2 now on diagonal stress hinder variation tendency, thus reaches the effect of antidetonation.Can be made adjustment and control to er damping by monitor control system (computer control system) simultaneously, realize the semi-active control to vibration.
This damping wall construction is simple, Path of Force Transfer is clear, can quick assembling and efficiently constructing; Other Intelligent shock absorption system relatively at present, this damping wall cost is low, be easy to safeguard.
