PhD student position in Concrete Structures

2019-11-29

Chalmers University of Technology, Department of Architecture and Civil Engineering is now looking for a PhD student who will study corrosion cracking by non-invasive, non-distructive imaging based methods combined with advanced numerical modelling. Ultimately, the project will lead to guidance on how the load-carrying capacity can be obtained from visual inspection. Thereby, the project will contribute to significant economic and environmental savings for society, preserving also large cultural values, as we with improved knowledge can repair and replace existing structures only when necessary, still guaranteeing the required structural safety.

Project description

The aim of the project is to provide knowledge required on how the structural safety of older structures should be assessed. More specifically, to link data from visual inspection, such as cracking and spalling, with the remaining load-carrying capacity of the reinforced concrete structure. In this project, we will integrate data from neutron and X-ray tomography to quantify the internal mechanisms in the sample during the corrosion process. These unique tomography data are obtained at the imaging beam line of the Institut Laue-Langevin (ILL) in Grenoble as part of an ongoing collaboration. Further, nonlinear finite element analyses will be used, describing volume expansion, granular behaviour of rust, porous zone, transport of rust through cracks, non-uniform corrosion, and frost. Thus, the combined action of all the mentioned phenomena will be studied.

The research is done in the research group Concrete Structures, which is part of the Division of Structural Engineering at the Department of Architecture and Civil Engineering. The research group is internationally well-known for its expertise in assessment of existing reinforced concrete structures. Other focus areas are the use of innovative materials in concrete such as fibres and textiles, and industrial construction.

Major responsibilities

Your major responsibility will be to carry out the PhD project and to conduct research in concrete structures. You will have the opportunity to influence the details of the research towards the needs of the project, with the possibility to combine experimental work with theoretical modelling. As a doctoral student, you will participate in doctoral courses and be involved in teaching activities. You will develop your skills in communicating scientific results, both to the public and industry and through scientific publications to the research community.

As a Ph.D. student you are employed by Chalmers and will receive a salary according to current salary agreements. The position is limited to maximum 5 years. A maximum of 20% of your time will be required for carrying out departmental duties, mainly teaching of undergraduate courses. The remaining time will be spent on your own courses and research, and you are expected to obtain a Ph.D. degree within 5 years (nominal time without department duties is 4 years).

Position summary

Full-time temporary employment. The position is limited to a maximum of five years.

Your qualifications

The successful applicant has a good knowledge of concrete structures and enjoys both experimental and modelling work. A suitable background is a Master of Science orresponding to at least 240 higher education credits (Swedish: civilingenjör) in civil engineering with good knowledge of structures, or an equivalent degree. You are expected to work relatively independently (although you will be a part of a research environment with several other researchers and Ph.D. students), have an ability to plan and organize your own work, to work in collaboration with others, and to be able to communicate your scientific results in English.

Knowledge of nonlinear finite element analysis and an interest in modelling and computer simulation are beneficial. Furthermore, knowledge of Python or Matlab, or experience from digital image processing, are beneficial but not required. It is, however, expected that the candidate is willing to develop this knowledge during the project.

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.
