Eco-composite wall structure is a unique structure which is composed of many kinds of materials. It is so complicated to calculate the dynamic performance of the structure that it is required to put forward a simplified dynamic calculation model. Based on the previous study of the group and relevant theories, this paper put forward a simplified model of the ecology composite wall structure in elastic stage for dynamic response analysis, and establishes the movement partial differential equations of the distributed parameter systems for the ecology composite wall every floor to calculate the modes and frequencies. In addition, the displacement of every top floor is taken as a bearing incentive, and the vibration superposition method is adopted to analyze the damping dynamic response of every floor of the ecology composite wall, dynamic response analysis on the whole composite wall is carried on and the results are compared with the preliminary shake table test results.Theory and experiment results show that the frequency of 1st mode and acceleration response curves of every floor agrees well with the experimental data, so the model has certain calculation precision and practicability which provides a better simplified and practical calculation method of the ecology composite wall structure in the elastic stage for the dynamic response.
