Torsional Design of Box Sections

[Rafat125]

Hi, can anyone give me any reference or materials regarding the design of concrete box sections (box girders) curved in plan? (i.e. subjected to torsional moment.)

Thanks in advance--

The Macgregor and Wight text has a decent discussion of torsion. I'm failing to recall if it specifically discusses boxed sections, but the mechanics should be the same.

Are they prestressed bridge girders?
