| Summary: | This thesis document was issued under the authority of another institution, not NPS. At the time it was written, a copy was added to the NPS Library collection for reasons not now known. It has been included in the digital archive for its historical value to NPS. Not believed to be a CIVINS (Civilian Institutions) title. === 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.
