Fibre-reinforced post-tension anchoring zone – an experimental comparison of reinforcement configurations

Prestressed concrete structures have numerous advantages over conventionally reinforced concrete, though the usage of post-tensioned structures has declined over the last two decades. An essential design detail in post-tensioned structures is the anchorage zones. In this study an experimental comparison is presented for post-tensioned anchorage zones. The study evaluates the load-deformation response and cracking of three different configurations. In total, six specimens are tested experimentally by subjecting them to centric loading until clear crack formations were observed. The evaluation and comparison of the three different configurations are done by comparing the data obtained from the tests. The results presented in this paper are expected to provide further knowledge to develop and improve the contemporary design approach and construction of bridges.
