| Abstract: | Using statics loadtest result, we expatiated the general process of structural statics finite element model updating. Based on chief influence factor analysis for updating optimization objective function construction, the technique of objective function construction is proposed, which is an overall consideration of the test load measure error, test response measure error and test response type difference （or numerical value great disparity） of the structure statics loadtest. And with application on a simply supported beam numerical examples analysis, this technique is confirmed. |
