摘要：
Parameters selection plays an important role in the model updating and a good parameters selection improves the efficiency of model updating. The sensitivity and the significance method are widely used for parameters selection. The theory and application are researched. A real structure was selected to research the parameters selection. The result shows these two methods can all be used in the simple structure and the significant method is more convenient for use in large finite element model. However, a new experiment design method is required to reduce the sampling space for significance method using in too many parameters condition.
