在对工程结构损伤识别问题进行研究的基础上，提出了基于有限元方法和同伦延拓法的损伤识别方法，并采用该方法对损伤简支梁进行了损伤程度的识别。
A new method was researched for structure 's damage identification on the basis of researching the damage problem of engineering structure . Based on the combination of finite element method and homotopy continuation algorithms , it identified the damage grade of beam with different kinds of damages .
