Abstract
Particle image velocimetry (PIV) is an optical method to measure full-field displacement of moving objects, with significant advantages over traditional method using labour intensive strain gauges. This paper introduces an application of PIV with single non-commercial digital camera, in a series of reinforced concrete four-pile cap shear experiments performed by the first author at University of Southampton, the UK during his PhD study. The PIV measurement for cap surface displacement and strain distribution helped to reveal the shear behaviour of reinforced concrete pile caps under wall loadings. A full PIV procedure and the derivation of displacement/strain data from PIV readings is explained.
This paper also presents an error analysis for the inherent random and system errors associated with PIV technology. Advice are made regarding the efficient way to improve the measurement accuracy for future implementation. Examples of the corrected output from PIV are given and compared with numerical modelling output.
