Abstract
Numerical analyses relating to real-scale research of prestressed crane girders were carried out. Modelled beams had a low transverse reinforcement ratio. Moreover, the cable anchorages did not have any corrosion protection. Numerical analyses were conducted in phases, to simulate prestressed member operation (according to the research). Also, to simulate cables’ anchorage failure, bonding transmission of the prestressing force and bonding anchorage of the tendons. A total of 29 numerical simulations were performed. Based on the calculation results, an analysis of the effect of the transverse reinforcement ratio and the effective prestressing force magnitude on the load carrying capacity of the girders was performed. Numerical analyses mapped experimental studies with satisfactory compliance. Therefore, analyses enabled research to be extended. Numerical analyses indicated, the reinforcement marginally affects the load carrying capacity of the investigated elements. Also, failure of the top cable’s anchorage negligibly influences the load bearing capacity. On the other hand, the failure of bottom cables’ anchorages significantly reduces the carrying capacity of the analysed elements.
