| Abstract: | The energy balance equation of an isolated structure is established at the moment of maximum earthquake responses.Expressions of elastic vibration energy and plastic energy for isolated layers and non-isolated layers are presented.Then,based on the energy principle,formulas for predicting earthquake responses are derived.Three numerical models,including a top-isolated structure,a storey-isolated structure and a base-isolated structure,are used to validate the accuracy of the predicted responses.Finally,the ... |
