采用有限元理论对桥梁结构进行监测和评估,通过动力试验进行模型修正,进而识别损伤,是桥梁结构健康监测和安全评估的重要手段。
Adopting the finite element theory to monitor and evaluate the bridge structure, modifying the model through the dynamic test, and then identifying the damage, is an important means to bridge structural health monitoring and safety assessment.
