Ph.D. position on: "Innovative and Advanced Slab Systems using Digital Fabrication Technologies" in Dübendorf

Traditional formwork for reinforced concrete structures can account for up to 50% of the total construction cost and 75% of the total construction time and is a major source of wastage in construction as it is often made of timber that is eventually discarded after a few time usage. To overcome the disadvantages of traditional formwork, this cutting-edge project concerns the development of an advanced slab system comprising a geometrically optimized stay-in-place 3D printed concrete formwork and cast-in-place reinforced concrete topping. It is anticipated that the developed system would lead to the construction of lightweight buildings with large material and labor cost savings and may serve as a stepping-stone towards digitization of the construction industry. 

Within this project, you will develop methods for prestressing 3D printed concrete formwork to improve its load-carrying capacity. Your work will entail the implementation of topology optimization methods on formwork to manufacture slabs with free-form geometries. The project involves finite element modeling, analytical solutions, small- and large-scale experiments for the structural evaluation of the developed slab system. The project aims to culminate in a large-scale pilot application. 

The doctoral thesis will be pursued in collaboration with research colleagues from Empa and ETH Zurich. The project will start upon mutual agreement, earliest by December 1st, 2022.

We are looking for a talented and motivated candidate with a Masters degree in Structural Engineering and a strong background in 3D concrete printing. Experience or interest in developing post-tensioning techniques for digital fabrication is also important. Additional skills, including experience in small and large-scale experimental testing, finite element modeling, and knowledge of structural topology optimization, would be an advantage. A strong desire and motivation to find cutting-edge and innovative solutions in the field of structural engineering are essential. The candidate should 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.
