摘要：
Deriving from the single free system, structural damage detection basing on fusion index of fourth-order displacement and eighth-order acceleration statistical moment by using updated model method is proposed. In this study, damage detection results of numerical simulation and shaking table test of a 12-story frame structure was analyzed and contrasted. Two different damage indice were compared with consideration of environment noise. And the recoded data of shaking table test was used to validate the establishment of the theoretical model. Three typical cases were selected for damage detection analysis. It is demonstrated that the fusion method by using displacement and acceleration statistical moment theory to conduct damage detection of frame structure is feasible and effective. © 2019, Science Press.
