PhD Position: Multi-scale Modelling and Experimental Assessment of Volumetrically Prestressed Concrete

About the role

A fully funded PhD position is offered at ETH Zurich and Empa within the SURPASS project, an EU Horizon research and innovation project (2027-2031) on adaptive strengthening and repair of ageing infrastructure. The work focuses on volumetrically prestressed concrete overlays made with Fe-SMA fibres, combining meso-scale modelling, structural simulations and large-scale experiments. The thesis director is Prof. Dr. Eleni Chatzi; day-to-day supervision is provided by Prof. Dr. Moslem Shahverdi and Dr. Saim Raza at Empa Dübendorf.

Key responsibilities

• Volumetric prestressing of cast and 3D-printable SURPASS overlays using Fe-SMA fibres.
• Meso-scale finite element modelling of prestressing mechanisms, including activation, recovery stress, prestress transfer and reactivation.
• Structural-scale simulation of SURPASS overlays in strengthened members, with parametric finite element analyses for surrogate models and digital twin support.
• Large-scale experimental assessment of volumetrically prestressed overlays for non-planar structures, such as tunnel linings, arch intrados and curved bridge soffits.

Required profile

• Master's degree in Structural Engineering or a related engineering field.
• Strong background in nonlinear finite element modelling, structural mechanics and concrete structures.
• Experience or interest in 3D concrete printing.
• Excellent oral and written English is mandatory; German is an advantage.

Required skills

• Nonlinear finite element modelling and structural mechanics.
• Advantageous: small and large-scale experimental investigations, shape memory alloys, and 3D concrete printing.

What we offer

• A fully funded PhD position for 48 months in a modern research environment with regular supervision.
• The position is available as soon as possible and should be filled by no later than 1 March 2027.

Applications must be submitted online through the employer's job portal with a letter of motivation, CV, certificates, diplomas and contact details of two referees; applications by e-mail or post will not be considered.
