Aim of this study is to present a contribution to the problem concerning with the optimal distribution of PZT actuators for the controllability of the static response of a Bernoulli-Euler beam under different boundary conditions. Following the assumptions relative to the Pin-Force model the actuation of a single PZT on the beam is considered equivalent to two concentrated moments with opposite signs acting at the edges of the couple of piezoelectric patches. To find the deflection of the beam the methodology founded on the concept of transfer finite elements (TFF) was adopted. Each element is activated by a single actuator and the objective is to undo the effects due to an uniform loading. An index that represents the electrical energy of the actuation has been introduced and the influence of the length the the number of the actuators to minimize that index was investigated. Furthermore simple optimization problems concerning with the choice of the number and size of the actuators are presented.
