Static And Seismic Time - History Response Analysis Of ADINA Gravity Dam

Now, with the frequent occurrence of earthquakes in recent years, for the seismic analysis of the problem more and more countries the researchers note. Seismic analysis and design studies on the gravity of great significance. In this paper, a more systematic understanding of the dynamic finite element analysis, the theory of rough understanding of fluid-structure coupling, dam-reservoir interaction. A detailed understanding of the local artificial boundary, In recognition of these principles, based on the use of finite element software ADINA finite element model was constructed of gravity to achieve the finite element method and the use of gravity and implemented in a finite element software ADINA viscoelastic artificial boundary of the spring-damper units setting, but also to study the gravity of the input and fits seismic waves seismic waves in the final detailed analysis of the time course of gravity static and seismic response analysis. In order to do the research in this paper, the following work:(1) on the dynamic finite element analysis of dam-reservoir interaction on the basis of the theory will be a more detailed understanding of dynamic finite element analysis focuses on modal superposition method, step by step integration method. Combined with ADINA simulation software to establish the basic theory of gravity based on these static model and dynamic analysis models. In the model the time to deal with some issues, such as:treatment of dam foundation, simulative water way, the problem of water in contact with the dam, each element mesh processing and the like.(2) when dealing with the border, we use a limited range in the infinite domain interception was analyzed, which is to question the role of foundation radiation damping relative processing. It was supported by the three-dimensional and two-dimensional elastic artificial boundary equation solving process based on artificial boundaries and viscous elastic sports Solutions Solutions scattering field, and it has been calculated viscoelastic artificial boundary parameters of the springs and dampers.(3) Learn more about seismic waves and seismic analysis of the basic theory and method. According to some SIMQKE GR use software to address conditions, thereby fitting relatively stable seismic waves, and then based on ADINA to simulate seismic waves here in the model to simulate the seismic analysis. After entering seismic waves of gravity to nine different critical points on three different gravity conditions and detailed analysis.
