Abstract
The accurate design of prestressed precast beams is correlated with the proper evaluation of construction and service stages. On usually are considered the following construction stages: casting, transfer of prestressing, storage time, transport and mounting stage. In the presented paper, it will be illustrated the stress development on the beams by altering the specific times between different construction and service stages as a result of using different construction technologies as well as a consequence by imposing in advance different requirements during the design phase. To highlight these particularities IDEA StatiCA software was used, and a comparison between various cases is presented.
