Abstract
This invention is related to a double X mild steel damper. It is composed of energy consuming steel board, angle iron, horizontal linking steel board. It has high initial steel degree and good capacity of energy consuming. This invention can be used on the support of the multi-floored building, and also between the girder and the wall. This damper has simple materials, easy way facture, and has economic and using values and will be broadly applied in the field of quake-proof framework.
Description
Technical field
The invention belongs to building engineering structure earthquake-proofing technique field, relate to a kind of double X-type mild steel damper.
Background technique
In recent years, China has obtained plentiful and substantial achievement in research having carried out number of research projects aspect shock insulation, vibration damping and the vibration control of engineering structure.Traditional earthquake resistant design is to resist geological process by the anti-seismic performance that strengthens structure itself, promptly with structure storage itself and earthquake energy to satisfy the structural seismic standard of setting up defences: little shake is not bad, and middle shake can be repaiied, no collapsing with strong earthquake.And this antidetonation mode lacks capacity of self-regulation, under uncertain geological process, do not satisfy the requirement of Security probably, and the structural vibration control technology provides a rational and effective approach for structural seismic.Wherein, energy-dissipating and shock-absorbing is to guide the seismic energy of input structure into the mechanism of special setting and element to be absorbed and dissipate as a kind of Passive Control measure, thereby can protect the safety of agent structure.
The energy-consumption shock-absorption device that has had at present is a lot, as steel energy comsuming device, friction energy dissipation device, viscous fluids energy comsuming device, intelligent energy comsuming device.Wherein the steel energy comsuming device mainly is to utilize the good plastic property in steel surrender back to absorb seismic energy, and the damper form made from steel is a lot, as adding damping and stiffness device, tapered steel energy-dissipating device, annulus steel energy comsuming device etc.Use the damper major advantage of steel manufacturing to comprise: simple, easily processing, the hysteresis stable performance of drawing materials, to be easy to replacing etc.Because damper is as a kind of energy-dissipating device, it in most cases is a kind of attached member as structure, the own drag of participation structure not, and the damper initial stiffness made from mild steel is low, how fully to improve the initial stiffness of mild steel damper, and develop novel steel damper in dual nature of its surrender back performance plasticity power consumption and have unusual meaning.
Summary of the invention
The present invention provides a kind of novel mild steel damper, its objective is to solve the low technical deficiency of initial stiffness in the existing mild steel class damper, and a kind of higher initial stiffness that has is provided, and has a kind of double X-type mild steel damper of better energy-dissipating property simultaneously.
Technological scheme of the present invention is as follows:
A kind of double X-type mild steel damper is connected steel plate and is formed by power consumption steel plate, angle steel, level.It is characterized in that: two X geometrical shapies are made on power consumption steel plate plane, the power consumption steel plate is connected steel plate with two levels up and down and angle steel connects as one by bolt or welding manner, the low carbon steel of tensile yield strength smaller or equal to 235Mpa is chosen in the suggestion of power consumption steel plate materials, has good plastic property to guarantee it.It should be noted that: the first, the power consumption steel plate is processed into two X-shaped shapes makes it the phenomenon of multiple spot surrender occur in the stressed stage, thereby has improved the distortion energy-dissipating property of damper greatly, two X geometrical shapies of the steel plate that will guarantee to consume energy in design physical dimension process; The second, double X-type mild steel damper stress form is stressed in the plane.The 3rd, to concentrate for avoiding stress, the wedge angle that the power consumption steel plate occurs all replaces with the fillet form.
Effect of the present invention and benefit are mainly reflected on the dual performance of double X-type mild steel damper: can be structure before the surrender of double X-type mild steel damper higher initial stiffness is provided; Has good plasticity energy-dissipating property after the surrender.The appearance of double X-type mild steel damper makes that initial stiffness is big, good these two characteristics of energy-dissipating property have obtained unification, also make because the power consumption system is single because of acting on, the higher problem that can not get fully using of cost is solved, will more be widely used in the seismic design of structures field.

Embodiment
Be described in detail most preferred embodiment of the present invention below in conjunction with technological scheme and accompanying drawing.
During concrete enforcement, at first, rectangular steel plates is processed into two X-shapeds, sharp corner occurs, make power consumption steel plate 2 all with the transition of fillet form; Secondly, processing bolt hole on power consumption steel plate 2, angle steel 3, horizontal steel plate 4; At last, with bolt 5 three is linked together.
Claims (1)
1. a double X-type mild steel damper is connected steel plate with level and is formed by power consumption steel plate, angle steel, it is characterized in that: double X-type is made on power consumption steel plate plane, and angle steel is connected steel plate and is the bolt connection with power consumption steel plate and level, also can take welding.
