Guo Guohui. Damage Assessment of Frame StructuresBased on Changes in Mode[J]. Journal of Civil and Environmental Engineering, 1998, 20(6): 79-82. DOI: 10.11835/j.issn.1674-4764.1998.06.016.
The method of structural damage assessment based on changes in eigenvalues has some defects.Therefore
this paper presents a method of damage assessment of frame structures based on changes in mode.The adaptability and efficiency of this method are discussed through computation simulation.The results indicate that this method is feasible.
