Abstract

In this paper we apply a previously developed algorithm to predict unfavourable lateral deformations of precast concrete beams. The algorithm is robust, i.e. there is no danger of false solutions or divergent behaviour, however this reliability requires a high computational effort. This latest is partially compansated by the parallel implementation of the algorithm, namely it can be used under the Grid. The algorithm applies the rules of the Eurocode 2 standard to include the special material properties of concrete such as creep. We developed also additional componentes (a user interface and a graphical application) to enable industrial users to carry out calculations easily via a web browser. In this paper we apply our method to predict unfavourable lateral deformations of prestressed bridge beams originating from the slight asymmetry of the prefabricating technology.
