At the present time, “sustainable development” is a key issue in a wide range of fields, including production technology, life-cycle management and the use of natural resources. It is also one of the most challenging goals in the construction industry. This applies not only to the design of new structures but also to the management of the huge stock of existing structures.
The objectives of this work package are to develop new bridge strengthening and upgrading techniques and enhance existing ones focusing on minimizing traffic disruption and environmental disturbance in densely populated cities.
The strengthening techniques considered should:
- result in considerable reductions in lane closures, traffic disruption and thereby expensive traffic management costs
- be material independent both with reference to the bridge to be strengthened (concrete, steel, composite) and with respect to the material used (e.g. CFRP, GFRP, SRP)
- consider the long-term performance of the strengthening schedule and provide sustainable alternatives to existing traditional strengthening methods in terms of efficiency, durability and environmental friendliness.
This project "Pantura WP5: Flexible techniques for maintenance and refurbishment of existing bridges" is related to the project Pantura - Low-disturbance sustainable urban construction.
The project is carried out at the Division of Structural Engineering in the research group Steel and Timber Structures.
