The new theory and new method of the analysis of intelligent structures were studied. Based on intelligent constitutive relation theory, instantaneous variational principle and spline dispersing, the electromechanical performance equation of the piezoelectric intelligent simply supported beam was established by the intelligent spline finite point method. Different loads, different material and different material constant values were considered. The method showed to be versatile and efficient comparing with the FEM ANSYS.
