Ability and combat a natural disaster performance and be particularly important, people also seeking always various methods effectively to mitigate and inhibit vibratory response to
The harm of engineering structure bring.The dampers using developing materials such as viscoelastic material, viscous fluids various in recent years achieve
Certain effectiveness in vibration suppression, but such material production damper in engineering application it is still necessary to overcome it is such as antifatigue, anti-aging,
The common problems such as durability, corrosion resistance and fluid damper leakage phenomenon that may be present.Marmem is
A kind of new function material, big with significant shape memory effect, super-elasticity and high damping characteristic and recoverable deformation,
The advantages that highly energy-consuming, good corrosion-resistant and fatigue durability and its tension-torsion effect is all good, develops and uses shape memory alloy material
Damper can overcome the problems of existing conventional damper.
Marmem (ShapeMemoryAlloy, abbreviation SMA) is a kind of novel functional material, has shape note
Recall characteristic, superelastic effect and high damping characteristic, is received great attention in vibration control of civil engineering structure field.Super-elasticity is
Refer to that alloy generates the strain much larger than its elastic limit strain amount under external force, this strain can be automatic extensive in unloading
It is multiple.SMA device has durability and good corrosion resistance, validity period limit for length, allows to deform big and deform compared with conventional apparatus
It the series of advantages such as can restore.
It can realize and subtract using the highly energy-consuming of marmem pseudoelasticity and the damper of large deformation self- recoverage latent structure
The self-healing dual function of shake and structure protects structure not by earthquake damage, it is desirable that damper is prior to knot in design
Structure is surrendered, and unidirectional deformation can only generally occur for marmem damper in the prior art, the scope of application compared with
It is narrow.The yield deformation of marmem and the length of marmem are directly proportional, marmem in existing damper
Length suffer from limitation, so that the hysteretic energy ability of damper be made to receive restriction.
