Advanced Analysis of existing reinforced and pre-stressed concrete bridges
Abstract
The road network in the region of Vienna, Lower Austria and Moravia faces major challenges: aging structures, increasing traffic loads, effects of climate change, new quality requirements and a limited budget for road infrastructure. In order to maintain a reliable road network, new, innovative approaches must be pursued. In particular, this also applies to bridge structures. Currently, their maintenance management is based on regular structure inspections. Damage is not discovered until obvious. This procedure is damage-based and reactive. Damage and problems of the structure, however, often already manifest themselves inside the structure, through the actual but often unknown effects on the structure. The bridges of the future should be able to provide information on their condition and development at an earlier stage and in addition to the structure inspections. The aim of the project "SAFEBRIDGE" is to design in-depth numerical reliability-oriented assessment methods for bridge systems (according to the ONB4008 Level III) and to make them accessible to a larger number of engineering offices as well as infrastructure operators in the Vienna, Lower Austria and Moravia regions. The in-depth numerical reliability-oriented assessment methodology provides relevant information and holistic evaluation of bridge systems and has a significant effect on the efficient and targeted use of the limited bridge maintenance budget. The core outputs of the project for the infrastructure operators (InfB.) and engineering community (IngG.) of the region Vienna, Lower Austria and Moravia are: (a) the creation of accessibility to the in-depth numerical statistical building blocks and reliability-oriented assessment methods for the holistic evaluation of bridge systems, (b) the creation of a guideline for the low-risk application of the in-depth procedures, and (c) the development of a sustainable training program. These three approaches have not been prepared to date in any of the European countries and worldwide for the IngG. and InfB., and are therefore classified as highly innovative. The in-depth numerical reliability-oriented assessment methods will be developed and presented for ten bridge objects from the Vienna, Lower Austria and Moravia region that are jointly selected with the Strat. Partners and subsequently they will be transferred to a guideline. Regular meetings provide know-how transfer to and from the strategic partners and calibration of the pilot training program based on the 10 selected case studies. The training program at the Univ. is after the project of the IngG. and SMEs. Since the maintenance, operation and evaluation of the infrastructure facilities is cross-border, the training / project should also be established.
