| Abstract: | Modal analysis method is used to discuss the location and identification of the damages to reinforced concrete structure due to corrosion and cracking.Real bearing condition of structures is identified according to measured modal frequencies of undamaged structures.The finite element model on in situ test structure is established.The method locating and identifying the damages to reinforced concrete structure due to corrosion and cracking is verified. |
