Abstract

The dynamic and earthquake response of simple models of ancient columns or colonnades is examined here. The influence on this response arising from the inclusion of shape memory alloy devices, based on wires having energy dissipation characteristics (SMADs), is also studied. The excessive rocking and sliding and subsequent collapse of the epistyle is an additional form of unstable response in addition to the excessive rocking, rotation and sliding of the individual columns. The insertion of these devices seems to inhibit, up to a point, unstable modes of response, whereas these identical model structures without the SMADs developed certain types of unstable response at lowe
