In this study, we discuss the dynamics of a type of hanging truss structural system consisting of rigid and wire members,\npart of which are SMA (shape memory alloy) wires. This kind of truss structure has the capability of vibration isolation\nand absorption. Characteristics of zero compressive stiffness of wire members, SMA wire members and hanging configuration\nof the structure itself contribute to the effect of vibration isolation. The hysteretic loop of SMA wires plays\na significant role in vibration attenuation. Mathematical models for this kind of dynamic problem are developed. Calculation\nprocess is introduced to take into account the mechanical characteristics of SMA and wire members. Dynamic\ncharacteristics are discussed; simultaneously, the effects of vibration isolation and attenuation have been confirmed. On\nthe basis of the numerical calculations, advantages of combinations of various types of wire members, including the truss\nunits having no bracing wires have been demonstrated.
