摘要: This paper presents the elastic buckling of column structures with a pair piezoelectric layers surface bonded on both sides columns. The governing equation coupling effect is first derived based assumed distribution electric potential in flexural direction layer and an eigenvalue problem solved using direct difference method. force excited by due to external voltage modelled as follower tensile paper. Such used enhance capacity structure. For columns different boundary conditions, results are presented show their variations respect location applied voltages. It was found structure could be enhanced effectively designing optimal layers.
