Software for Curved Girder Bridges with Straddle Bent Piers

[bgarbasz]

I was wondering if anyone would be able to provide some recommendations on the best software to design a multi span horizontally curved steel bridge with steel straddle bent pier cap beams. The steel girders will most likely be framed into the web of the steel straddle bent pier cap, which will be supported at each end by a single concrete column.

Is there a commercially available sofware program that would be able to incoporate the steel straddle bent pier cap? Would a combination of programs be required to perform the analysis? We currenly utilize DESCUS to design our horizonally curved girder bridges but I wonder if given this type of structure if there isnt something better out there.

Any input would be greatly appreciated.

I've replied in the structural forum. MDX and PC-SIMON are two other steel plate girder programs that are available for both straight and curved girder applciations.

Also, please make sure that your clients knows that they will end up with a fracture critical bridge by using a steel straddle beam. Many DOT's do not like steel straddle beams for this reason. Concrete straddle beams are not FCM.
