Abstract: The Inner Tracker detector (ITk), part of the ATLAS High-Luminosity LHC Upgrade, consists of pixel and strips sensors, held in place by rigid structures designed to ensure very high stiffness and radiation length. The main structure, designed at LBNL, consists of a 3 mm thick, 6 m long and 2 m wide carbon fiber cylinder. The critical connections of this cylinder to the external cryostat and the inner structures were tested against nominal and ultimate loads, monitoring the deformations with strain gauges and LVDTs. The failure load was then measured: the local debonding of a large titanium insert caused the structure to collapse. Here we present the main experimental results, comparing them with numerical and analytical models that allowed us to predict the failure load with good accuracy
