In order to represent the result of structural dynamic response simulation analysis better, we are researching on taking advantage of the new method for simulation representation that combines both multimedia representation technology and engineering structural analysis algorithm. In this paper, it is presented how to get optimum representation results using the volume rendering, rendering algorithm for structural deformation, representation method for quantitative data, fast rendering and method to generate continuous simulation scene, especially using the combined method mentioned hereinbefore. The practical effect using the method proposed in this paper in simulating reinforced concrete frame structural dynamic response under seism is illuminated in detail. The efficiency of this method is verified. Simulating experiments are carried out on PC, which are based on Windows 2000 operation system and use OpenGL as developing tools, exhibits the broad prospect of using and developing multimedia simulation technology.
