Overview
Curved girder analysis is not easy like straight girders, and only limited software can handle this problem. Dr. Watanabe developed a full influence line theory for three-span continuous curved girders. The detailed theory is quite interesting, but only the methodology of how to use his methods is discussed in the article. His methods give an exact solution for a symmetric three-span curved girder, and the warping effects are not included. As always, start with an example. The input and output are self-explanatory and detailed discussion is not provided.
Input
Dr. Watanabe's method requires only five inputs.
Side span angle = 25°
Center span angle = 40°
Side span stiffness ratio
Center span stiffness ratio
Moment of inertia ratio
Influence line due to point load
Influence line due to torsional moment
