Monitoring infrastructures is becoming an important and challenging issue. In Italy, the
heritage consists of more than 60,000 bridges, which need to be inspected and detected in …

A modeling strategy has been developed that permits coarse-precision terrestrial laser
scanner observations to be used to accurately measure vertical deflections of deforming …

Civil engineering material testing includes a wide range of applications requiring the
determination of the three-dimensional shape of an object and changes thereof. Large …

The aim of this study is to develop a novel computer-aided method for the prediction of the
deflection of reinforced concrete beams (DRCB) under concentrated loads. To this end, in …

A videogrammetric technique is proposed for measuring three-dimensional structural
vibration response in the laboratory. The technique is based on the principles of close-range …

An image sequence analysis procedure is developed to quantitatively analyze complex
multiple crack patterns in tension tests of fiber-reinforced composite specimens. Planar …

The paper presents an Image-based Method for Crack Analysis (IMCA) which is capable of
processing a sequence of digital imagery to perform a twofold task:(i) the extraction of crack …

Due to the aging global civil infrastructure (eg bridges), there is a critical need for monitoring
