3. NATURE OF PHYSICAL PROBLEM SOLVED - Elastic analysis of piping system.


4. METHOD OF SOLUTION - The flexibility matrix A is first calculated, which is a 6 x 6 matrix known by the characteristics of the piping system. The free thermal expansion vector is then calculated at one anchor. This vector should be zero. Therefore, the force vector F at the anchor is determined by the inverse flexibility matrix a**(-1), and the free thermal expansion vector is determined by Fuchs's law.


5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM -
Maximum number of pipings - 20
Maximum number of branches - 20
Maximum number of pipes - 20
Characteristics of anchor - rigid (except that one anchor is allowed to be displacement-free and force-restricted).


6. TYPICAL RUNNING TIME - Less than one minute.


7. UNUSUAL FEATURES OF THE PROGRAM - This program can deal with the analysis of piping systems composed of any number of branches, curved pipes with any curvatures and straight pipes with enlarging diameters.
