| Abstract: | Structural damage detection is an active research field in the structural engineering disciplines,and it has a broad and far-reaching significance.This paper uses the software SolidWorks to complete the numerical model of the frame structure.By changing the degree and the location of the model damage,it carries out vibration test analysis and obtains the natural frequency comparison of the undamaged model and the damaged model.This paper sums up the law for the changes of characteristic parameters when fram... |
