Have you ever seen a wall cyclic shear test? We tested three full-scale reinforced concrete walls at UCSD with post-installed anchors to understand anchorage seismic performance in mixed-mode cracked concrete, with the support of Hilti.
Wonder how concrete wall specimens are built? Look at this video, when we built two low aspect ratio reinforces concrete shear walls at UCSD. All those cables are that you see are the strain gauges, sensors used to measure the strain in the reinforcement.
