Ph.D. position on Compression-Dominant 3D-Printed Concrete Structural Systems for Buildings

Materials science and technology are our passion. With our cutting-edge research, Empa's around 1,100 employees make essential contributions to the well-being of society for a future worth living. Empa is a research institution of the ETH Domain.Our Structural Engineering Research Laboratory develops new materials, systems, and manufacturing technics for civil infrastructure use. It is one of the biggest and most up-to-date structural laboratories in Europe, equipped with excellent testing facilities required for large-scale experiments. Some of its research endeavors to resolve open issues / questions related to 3D concrete printing. The primary goal is to develop innovative and attractive solutions for the problems hindering the wide-scale adoption of digital fabrication methods in the construction industry

In this project you will focus on structural form finding of compression-dominated structural systems for buildings. The structural system will be composed of discrete blocks made up of 3D printed concrete. Compression-dominant behavior will be achieved by designing an optimized structural form that directs forces primarily into compression paths, minimizing tensile stresses. This behavior will be further enhanced through mechanically induced compression using iron-based shape memory alloy (Fe-SMA) reinforcement. You will perform the following tasks :  Topology optimization of discrete blocks to ensure material-efficient design Investigation of the mechanical strength characteristics of discrete blocks with small-scale experiments Development of innovative joining techniques for discrete blocks, with a focus on potential for deconstruction Large-scale experimental testing of compression dominant structural systems under quasi-static loading Your profile

You have a Master's degree in structural engineering with a strong background in structural form-finding and topology optmization. Experience or interest in 3D concrete printing is also important. Additional skills, including experience in small and large-scale experimental testing, finite element modeling, and knowledge of shape memory alloys, would be an advantage. A strong desire and motivation to find cutting-edge and innovative solutions in the field of structural engineering are essential. You have a clear interest in working in an application-oriented research environment in close collaboration with our industrial and academic partners. Good knowledge of English (oral and written) is mandatory, knowledge of German would be an advantage.

We offer a multifaceted, challenging, and fully funded Ph.D. position for 48 months in a modern research environment with excellent infrastructure. The position is available as soon as possible but should be filled by no later than April 1, 2025.
