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
