Adaptive imperfect column with piezoelectric actuators
This paper discusses the stability of long imperfect adaptive (or smart) columns. The mechanics of a smart column having piezoelectric elements as active elements is introduced first. Then, the governing differential equation of the adaptive column is presented. A numerical example is given to show the capability of active piezo-ceramic elements in enhancing structural stability of long imperfect column. Obtained numerical results show improved stability performance of the adaptive column in comparison with the passive one. It is possible to straighten initially imperfected columns using surface attached active elements.
