Abstract:
      The Pseudo Excitation Method (PEM)has received much attention due to its outstanding advantages. It is highly efficient and necessarily involves the cross correlation terms both between the participant modes and between the excitations; so that it is theoretically exact. In addition, it is very easy to develop the analysis functions of structural stationary or non stationary random reponse on any FEM program with the function of harmonic or time history analysis. This article compares the efficiency and adaptability between PEM and the conventional method in order to make PEM be better understood and applied.
