F) ABSTRACT: The title of this work refers to a fundamental scientific research about bridging the gap between the microstructure of concrete and the studied traffic infrastructure. It has been carried out in the framework of a joint research project of the Institute for Mechanics of Materials and Structures of Vienna University of Technology and the Department of Geotechnical Engineering of Tongji University, Shanghai. It reads as: bridging the gap by means of multiscale structural analysis. Four different topics are treated in the framework of the general subject of this report. The first two topics deal with the analysis of traffic infrastructure, subjected to exceptional load cases. The first topic is on multiscale analysis of thermal stresses in concrete pavements due to sudden temperature changes and the second one is on microstructural analysis of the impact and blast loading in tunnel linings. The last two topics deal with reinforced concrete hinges in different types of traffic infrastructure. One of them is on multiscale structural analysis of segmented tunnel rings used in mechanized tunneling and the other one on experiments and Finite Element modeling of reinforced concrete hinges used in integral bridge construction. |
