The Research Project

Currently, there are numerous methods and techniques aimed at extending the service life or repair existing structural elements. Bolting or welding of steel plates, applying CFRP and external prestressed tendons are the most common among these techniques. Nevertheless, these techniques have limitations and disadvantages such as increasing the self-weight of the structure, introducing stress concentration, reducing the fatigue lie of the structure or high labour and materials cost. Among the recently developed repairing and upgrading methods is the so-called Local Post-Tensioning (LPT) which increases the stiffness and the load carrying capacity of the structural member through adding reinforcing steel bars to a segment of the beam.

This project will be investigating the use of innovative strengthening and upgrading techniques (or their combinations) in order to extend the service life and restore the load carrying capacity of various steel, concrete or composite structural elements. The candidate will be using nonlinear Finite Element Analysis, experiments, or both to validate theoretical findings.
