The earthquake in Taiwan during 1999 was their largest of the
century, with a magnitude of 7.3. This
paper details a survey of damage to the stay rods and steel liners of the 250m
high Taichung chimneys. It
concludes that the dynamic interaction between liner and shell is an important
factor in its behaviour under such extreme loading.
Design methods should take account of the possibility that stay rods and
other shell supports may be damaged during an earthquake so that the normal
assumption of working lateral restraint does not apply.
Normally it is assumed that any such damage can be repaired before a
major problem occurs.
