Abstract :
This paper presents the results of the validation of a prototype vision measurement system for use in experiments on civil engineering structures. The system is tested against a uni-axial earthquake shake table designed to hold full-size masonry walls. We compare the reference earthquake signal, the forcing signal, and the observed signal in terms of displacement with time.
