摘要：

In the paper the dynamics of a structural elastic-plastic frame, endowed with pseudoelastic shape memory alloy (SMA) tendons and subject to some vertical and horizontal loading conditions, are analysed. A wide numerical investigation is carried out in order to show how SMAs are able, more than ordinary or other special materials, to give to the structure good dissipative skill and high re-centering capacity. At this aim, some comparisons are presented with the cases of a simple oscillator, of a frame with elastic-plastic tendons and of a frame with unilateral elastic plastic tendons unable to sustain compression.
