Footbridge Berlin 2017, 6th International Footbridge Conference, 2017-09-06/09-08, Berlin (DE), DOI: 10.24904/footbridge2017.09352, pp.1-6, 2017Abstract: The paper presents a new type of emergency bridge, which can be quickly constructed in case of damages after a natural disaster. The concept of the bridge is based on the application of scissor-type mechanism, which provides its rapid deployment. In case of deployable structures apart from static analysis of different configurations of expansion, it is very important to investigate the dynamic behavior of the system. High compliance and flexibility of the scissors-type bridge may influence user's comfort and safety in case of heavy dynamic loads such as human induced impacts, wind gusts or earthquakes. Up to now, the authors constructed several types of the experimental MBs. The presented research reviews fundamental numerical and experimental results for the Mobile Bridge 4.0. Experimental testing included strain and acceleration measurements in free and forced loading conditions. From these results, it was possible to estimate basic mechanics characteristics, that is statics and dynamic property, of the bridge. The conducted research allows for a better and safer design of the structure of the Mobile Bridge.
