摘要：
Based on recursive stochastic finite element method a damage identification method of random structures is developed. Control equations about random damage index are built up after random damage index is defined. Structural uncertainty and measurement noise are both considered in the control equations. Statistics of random damage index are obtained after the control equations are solved utilizing recursive stochastic finite element method. The results show that structural damages can be identified while model errors and measurement noise are both considered. It is also found that the method presented has the same effectiveness as Monte-Carlo simulation method for identifying damages of random structures in wide range of random fluctuation.
