The cyclic characteristics of column base = the behavior of column base under cyclic loading.
Slip-type column base = under cyclic loading, due to the plastic elongation of anchor bolts, there will be a small gap between nuts and base pate,as a result, the friction between the nuts and base plate no longer exists, so, "slip" could occur between the nuts and base plate.That is why the author called them "slip-type" column base.
The authors of that paper invented a device which consists of a wedge and a spring.This wedge will fill up in the "small gap" between the nuts and the base plate, so, the friction will always be there and the column base will always be "non-slip".
With "non-slip" condition established, the authors then presented their findings about restoring forces in the anchor bolts.
Hope this will help. 作者:
