New doctoral dissertation
VILNIUS TECH Library invites you to follow the published new dissertations.
The dissertation „Constitutive bond-slip modelling of reinforced concrete members at service load“ („Fizikinis gelžbetoninių elementų sukibimo įtempių ir slinkties ryšio modeliavimas esant eksploatacinei apkrovai“) prepared by VILNIUS TECH, Alinda Dey. The dissertation was prepared in 2019–2023, supervisor – Prof. Dr Habil. Gintaris Kaklauskas.
The dissertation will be defended at the public meeting of the Dissertation Defence Council of the Scientific Field of Civil Engineering in the Senate Hall of Vilnius Gediminas Technical University at 10 a. m. on 2 October 2023.
The current dissertation aims to introduce a new interaction model between concrete and reinforcement to effectively address the inner mechanism of Reinforced Concrete (RC) structures.
For investigating the concrete-reinforcement interaction, traditional methods have typically dealt with a constant bonding relationship or a perfect interaction between two materials. This can further lead to numerous models that lack consistency and compatibility with one another. However, current research advocates for implementing the stress transfer methodology, which suggests the presence of force exchange between the reinforcement bars and the surrounding concrete, in other words, the bond stress. The present study develops a new model that establishes the ascending part of a bond–slip model. It is an essential step towards a constitutive bond–slip model in future, which will be able to accurately predict the serviceability performance of RC members, such as deflection, crack spacing/width etc.
