| 摘 要： | An experimental program was undertaken to test the feasibility to detect the occurrence of structural damage using a modified mode shape difference technique. The vibration response of a steel beam fixed at one end and hinged at the other was obtained for the intact and damage conditions. Modal analysis was performed to extract the frequencies and mode shapes. The method shows a good potential in detection of occurrence and location of damage.

| Abstract: | An experimental program was undertaken to test the feasibility to detect the occurrence of structural damage using a modified
mode shape difference technique. The vibration response of a steel beam fixed at one end and hinged at the other was obtained
for the intact and damage conditions. Modal analysis was performed to extract the frequencies and mode shapes. The method
shows a good potential in detection of occurrence and location of damage. |
