ABSTRACT
The University Bridge in Bydgoszcz is a cable-stayed structure with a controversial architectural and structural design. The Bridge was closed due to a design flaw revealed during an inspection in 2020. The high risk of a structural failure was the main reason for the closure of the facility. Key parts of the bridge underwent reinforcement in 2021. Despite successful repairs, discussions about the repair actions remain ongoing. The bridge closure has been challenged by opinions and studies suggesting other solutions. This paper addresses issues related to the assessment of the load-bearing capacity of the bridge. As part of the theoretical analysis, a global FEM model of the bridge structure was prepared. A model of the anchoring nodes of the cables was then created, using shell elements. Additionally, new material tests were conducted. Crucial to the assessment were plastic-phase low-cycle steel strength tests and monitoring data, which indicated adverse thermal effects.
