Description
Summary:Obviously several simplifying assumptions are used in a multitude of analytical methods available to structural analysts. Loading tests are habitually necessary, especially in the case of bridge superstructures of unusual conception, with the main purpose to verify calculation model and assumptions of bridge designer as well as suitability of transformation model. To satisfy all required code criteria still more sophisticated analyses are needed. In order to assure the safety under construction of significant bridges, monitoring is also executed to measure and analyse in site data. Also information significant for long term behaviour of structures is being collected. Especially material properties are controlled, rheological effects checked and straining variation recorded. In the paper, quite uncommon bridge superstructures are presented. The computer modelling is discussed and experimental assessment given.
