Strengthening of anchor channels on the concrete surface
For the installation of curtain wall systems, the positions of anchor channels gradually move closer to the edge of the concrete slabs. But close to the edge of the slab, conventional supplementary reinforcements have problems to redistribute the loads to the reinforcement due to the short bond length that is available after concrete edge failure occurred. Therefore, tests have been conducted to investigate the behaviour of anchors channels, close to the edge. To achieve this, a strengthening system on the surface of the concrete with post installed fasteners was developed. First results indicate a high potential for strengthening the channels close to the edge under shear load. With these test results numerical simulations with Atena Science were performed and, after its calibration, the model was used for further investigation.
