Theory and Test Investigation of Damage Detection and Assessment of RC Columns

This paper investigates the relationship of dynamic and static characteristics of RC columns under eccentric loading and the vibration testing method of the damage assessment of RC structures. Based on the study of the tests,a simplified computational model of the tested columns with two springs at both ends and an identificationmethod on the boundary bearing stiffness of the system model are presented.Accordingto the tested frequences,a single parameter method is proposed for identificating thestiffness of the columns. Satisfactory results are achieved from the damage assessment ofthe columns,which is based on both the static and the dynamic test results.
