Method of application of moment distribution to solution of arched bents

Abstract

A method of applying the principles of mement distribution to parabolic arched bents is presented here-in. The primary object has been to plot influence lines for the fixed-end moments, the horizontal reactions, and the vertical reactions at the ends of fixed-arches of any span length and rise/span ratio. These curves were computed by the conjugate structure method of analysis developed by Joseph S. Kinney, D.C.S.; Associate Professor of Structural Engineering, Rensselaer Polytechnic Institute, Troy, N,Y. The authors claim no originality in regard to the concept of applying moment distribution to al'ches since it was recognized by Hardy Cross when he first presented his method, and is the basis of a similar work presented by Cain for one span length only.
