요약 | Presented in this dissertation is an energy dissipation analysis framework for SSI. The issues of energy analysis in current practice are pointed out. As a commonly missed term in literature, plastic free energy is introduced with explanations on its physical nature. Energy dissipation due to material inelasticity, for solids and structural elements, and viscous damping are properly modeled. Theory and formulation of each energy term is derived based on the principles of thermodynamics. The topics of energy input and radiation damping are also addressed. Equation of calculating numerical energy dissipation for Newmark algorithm is derived. System energy fluctuation, or even production, could happen if inappropriate simulation parameters or time increment is used. It is suggested that numerical energy conservationshould always be checked.The presented energy analysis framework is implemented in the Real-ESSI Simulator for modeling and simulation, and visualized using ParaView with Real-ESSI plug-in. Material- and element-level numerical examples for energy dissipation due to material inelasticity, viscous damping, and/or numerical damping are developed and discussed. It is shown that the proposed energy computation framework does follow the two principles of thermodynamics, energy conservation and nonnegative energy dissipation, at all times.Large-scale, practical engineering examples are analyzed using the developed energy framework. The cases of reinforced shear wall, UNR soil box, and nuclear power plant demonstrate the full capability of energy dissipation analysis It is illustrated that the obtained energy analysis results can be directly used for the evaluation and optimization of SSI system designs. |
