Abstract
Until the advent of the high-speed computer, engineers have spent
untold hours with monotonous and lengthy computations when they have
attempted analytical solutions of piping flexibility for even moderately
simple configurations. Therefore, due to the complexity of this problem,
several companies in both the United States and Europe are
using model tests today as both an accepted independent method of piping
flexibility analysis and as a check on analytical results. Heretofore,
model test systems have utilized direct force-measuring instruments
at the extremities of the branches. This thesis describes a method by
which translational and angular deflection measurements are made a
distance from the anchored ends so that with these displacements, reaction
forces and moments may be computed at the extremities by use of
simple statics and cantilever beam deflection formulas. The thesis also
describes a practical and simple device to accomplish this purpose,
reports on actual tests of several typical configurations, and compares
the results so obtained with those given by analytical solution.
