Automated analysis and design of Super-Tee bridges

![CDATA[Super-Tee bridges comprise a very high percentage of the bridge stock in Australia. The geometry, construction sequence and loading of Super-Tee bridges can be characterised by a comparatively small number of parameters. These parameters can be used as a basis for a sophisticated computer model of such a bridge. Using only a few basic assumptions, the design of Super-Tee bridges can be standardised to a very high degree. A pre-processor has been developed which supports the definition of these parameters and which prepares the corresponding model data for a finite element analysis of Super-Tee bridges. Among other features the analysis of the model includes a construction stage simulation, all relevant loading according to AS5100 including traffic loading, pre-stressing effects including time-dependent effects etc. The results of this analysis are then used for an automated design check of the bridge according to AS5100 and the generation of an automated report. The model data can then be transferred to a CAD system for the final generation of drawings. The complete process is fully integrated into one single bridge design software package.]]
