Damage Detection of Hysteretic Structures with a Pinching Effect

AbstractSome civil engineering structures, such as RC frames, exhibit hysteretic behavior when subject to dynamic loads, such as earthquakes. The identification of hysteretic systems with stiffness and strength degradations is a practical but challenging problem encountered in the engineering field. A recently developed technique, referred to as the adaptive quadratic sum-square error with unknown inputs (AQSSE-UI), is capable of identifying time-dependent parameters of hysteretic structures. In this paper, the AQSSE-UI technique is applied to the parametric identification of hysteretic RC frames with stiffness and strength degradations and with the pinching effect. The performance of the AQSSE-UI technique will be demonstrated by the experimental data. A 1/3-scaled 2-story RC frame has been tested experimentally on the shake table at the National Center for Research on Earthquake Engineering (NCREE), Taiwan. This 2-story RC frame was subject to different levels of ground excitations back to back. The str...
