Experiments for seismic damage detection of a RC frame using ambient and forced vibration records
This paper presents an experimental study conducted on a two-story RC frame that was progressively damaged until it reached a significant structural damage. The RC frame was subjected to increasing dynamic load stages typical of growing-intensity earthquake ground motions. The frame was excited with a testing pendulum, which is a device that excited the structure attached to the pendulum platform with a harmonic motion along one horizontal direction at selected frequencies. For each damage level, ambient and forced vibration tests were performed, and dynamic properties of the frame were estimated. It was possible to characterize the damage level of the RC frame in terms of the simple statistical correlation between a pair of frequency response functions obtained for the initial damage condition and the subsequent stages.
