Longitudinal and transverse analysis of multi-cell pre-stressed concrete box girder

In present work, multi cell pres-stressed concrete box girder with simply supported ends has been analyzed using finite element models. SAP2000 bridge modeller has been employed for modeling box girder with pre-stressing cables. Pre-stressing force and losses have been included in the modelling. An iterative procedure for time dependent losses such as due to creep and shrinkage has been developed and used in the bridge analysis using the aforementioned software. To perform transverse analysis of box girder, simplified models are developed in finite element framework, and the results have been compared with conventional moment distribution and effective width method used in design practice. It has been found that rigid link element model, which is connected between the transverse frames, is more able to predict improved behaviour than simple frame element. However, for live load analysis of three-cell pre-stressed concrete box girder, three dimensional finite element frame model gives closer estimate to the existing width method.
