Presenter: Lukasz Wojnarski, Arup

Lukasz Wojnarski is an Associate Director at Arup in the UK who specialises in bridge design. He has led the design of complex highway and rail bridges on prominent infrastructure projects across the globe. His projects include major sea-crossings, cable-stayed, segmental and high-speed rail bridges. Lukasz is an enthusiastic promoter of segmental bridges and has presented and published articles through the IABSE, CBDG and ICE conferences and journals. He recently joined a team of UK experts working to update the UK National Annex to Eurocode EC2, where he focuses on the design of concrete bridges.

Lukasz will present on segmental bridges which are designed with external tendons only (no internal prestressing). He will discuss design and construction aspects of bridges with external tendons including the pros and cons of this approach using case study examples. He will detail how this concept could support the development of more sustainable bridges using circular design principles by re-using structural materials and components.
