In order to establish an accurate analysis method for the response of viscoelastic damping energy dissipation structure system, a precise integration scheme for the uniform and non-uniform response of the generalized Maxwell damping energy dissipation system is proposed based on the virtual excitation method. Firstly, the generalized Maxwell damping energy dissipation structure model with braces is constructed, and the dynamic equation of the structure is established by the method of order expansion. Secondly, based on the efficient virtual excitation method, the general precise scheme of non-uniform precise integration is proposed, and eight specific classical precise schemes of amplitude modulation precise integration are established. This method has the characteristics of wide application, convenience and representativeness. It provides a method for the uniform and non-uniform response analysis of viscoelastic energy dissipation system.
