摘要
阐述了利用静载试验成果、进行结构静力有限元模型修正的一般的过程,在分析其修正优化目标函数构造主要影响因素的基础上,提出了综合考虑结构试验荷载测试误差、静力试验响应测试误差和响应类型差异(数值大小差异)的目标函数构造方法,并通过简支梁静载试验的数值算例进行了应用验证.
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.
