The job is to model a steel bridge on SAP2000, or GSA or any other modelling program that would yield results showing the stress/strain on individual members and size members where possible (i.e. showing bending moment diagrams & shear diagrams). It would be great to model the forces acting on members during construction as well, but this is both cost and time dependent as this part of the project needs to be completed by Monday 14th of March 2011. The bridge has been built on AutoCAD already, so only needs the joints, the members and the forces acting on the structure specified. The model itself doesn't have to be overly accurate, but as long as it gives reasonable results the client would be much appreciative.
