BEHAVIOURAL INVESTIGATION OF PRESTRESSED CONCRETE BRIDGES HAVING BOX GIRDER WITH THREE CELLS
Post-tensioned, pre-stressed bridges are characterized by better stability and performance. The stress distribution in both directions, longitudinal “X” and transverse “Y“, of Box-Girder bridges is non-uniform, so it has complex behaviour. Recently there are much software for the design and analysis of bridges. Using software for bridges’ design is much better than the manual procedure. This paper involves modelling and analysis of a Box-Girder with three different-shaped, post-tensioned cells. Three variable shapes of multi-cell Box-Girders “Vertical-exterior girder, slopped-exterior girder and exterior girder with maximum slope” with the same area and different depths (2, 2.3 and 2.6m) were modelled and analysed using CSI-Bridge program, 2017-version. The analysis is carried under dead load, moving live load (according to the code of loading in Egypt), and pre-stressed load. Some results such as deflection and longitudinal stress were discussed and analysed.
