Explains how a FOCAL program can be used to solve difficult multianchor pipe stress problems. Presents a 6-anchor problem that will run in a half-hour on a small micro. Gives a general discussion of the problem with a little history behind some of the formulas. Other parts of the series will offer the FOCAL program; a typical 6-anchor example showing how to enter data and how to run the program; and a very simple single plane, 3-anchor example. The calculation method involves dividing a piping system into branches and trunk pieces. Each branch is broken up into members consisting of a piece of straight pipe and half of the elbow which is simulated by a short tangent, as shown in a diagram. A flexibility matrix is calculated for every member, and these 6 X 7 matrices are all knitted together to produce one 6 X 7 matrix. Tables give knitting logic and unraveling logic.
