The general theory of beams curved in plan with torsional restraint at the supports is explained, with particular reference to prestress loading. It is proved that the torsional moments due to prestress loading are solely dependent on the support bending moments, and the conditions of concordancy are formulated for a circularly curved beam. It is suggested that for most practical cases the support bending moments in circularly curved beams can be calculated to sufficient accuracy assuming the beam is straight, and the order of accuracy is given
