Simplified Method of Analysis of Reactions Developed by Expansion in a Three-Anchor Piping System

Existing methods of stress analysis in a three-dimensional piping system fully restrained at three points involve the predetermination of 78 coefficients, and the solution of 12 simultaneous equations. The author proposes a method which reduces the complicated three-anchor problem virtually to a simple two-anchor problem, involving only 21 constant coefficients and the determination of 6 equations. Actually, only routine tabulated computations are required by this method.
