For sustainment of concrete structures and the durable and sustainable design of concrete structures, a better understanding of the cracking of concrete is of major importance. At the unit Structural Engineering and Design a research will be started to improve the durability and sustainable application of concrete structures in civil workst.
A large part of the Dutch civil works consists of reinforced concrete structures. The cracking that occurs in these, is a crucial factor for the design life for new structures and the remaining lifespan for existing structures. An accurate determination method that correctly predicts the crack formation in new structures and that can (partly) explain crack patterns in existing structures, is therefore extremely important for both the design and maintenance task. However, crack formation in concrete is a complex stochastic process. Dozens of models have been developed for this, but it is insufficiently clear which of these, predicts actual cracking the most accurate. In any case, it’s the experience that the method laid down in the present Eurocode 2 is less clear-cut than the method used in the latest Dutch national standard. This especially when the cracking is due to the restrained of imposed deformations and the cracking pattern is not fully developed.
We are looking for a PhD candidate with the capacity to set up a data base with results of crack width experiments and an overview of relevant calculation methods for crack width. After this a data analysis should be performed to select the most accurate models. Finally, one of the models can be revalidated based on knowledge of the behaviour of reinforced and prestressed concrete due to external loads and restrained deformations.
The research will be performed within the chair of Sustainment of Concrete Structure which is part of the unit Structural Engineering and Design. The work will be done in close cooperation with the chairs of Concrete Structures and Applied Mechanics in which a successful and growing group of young researchers is active.
