Abstract:
Recent advancements in measurement technologies make it possible to record the full field displacements and strains on the surface of test specimens, as well as to examine internal composition including the progression of cracking and other forms of damage. This data can greatly advance design code provisions, as well as support the creation, calibration, and validation of more complete analytical and numerical models. This paper presents the authors experience in the use and development of increasingly sophisticated measurement technologies over the duration of the 30 years that he has been conducting experimental research on structural concrete. The most advanced technologies that are discussed include coordinate measurement machines, digital photogrammetry, digital image correlation, and X-ray-micro-tomography. The paper will also introduce advancements and challenges to the post-processing of this complex and voluminous data for advancing models and practice.
