Analysis of shear transfer actions in reinforced concrete members using refined measurement techniques

Detailed investigations on the role of the shear transfer actions in members without transverse reinforcement have traditionally been limited due to the possibilities offered by conventional measurement techniques. The main difficulty of such conventional techniques has been tracking the crack pattern and its associated kinematics (crack opening and sliding) during the process of failure. This situation has changed in the last years, with the introduction of photogrammetric measurement techniques. This technique allows obtaining very detailed measurements with high acquisition frequency, allowing a suitable tracking of the cracking process.
