RE: circular beams

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Basic Structural Analysis by Kurt H. Gerstle, 1974 has a few pages on Curved
Structures In Space and also a couple of pages on Three-Dimensional
Structures. In the Curved Structures In Space section there is an example of
how to determine the internal forces and moments along a helicoidal
cantilevered girder.

Subject: circular beams

i am looking for some basic text or reference on curved beam
behavior/theory. loading both parallel and normal to radius of curvature. 

i am working on a couple of buildings that have significant framing that is
swept (circular) in plan. one is concrete and one is steel. aside from fea
methods, i want to check and ballpark the forces/stresses. 

the only references i have found on the topic of swept beams are for
compisite steel bridge girders 
and in rouark's. the bridge stuff is useless to me and the methods in
rouark's are not exacly quick. 

any and all help is appreciated.
