PROBLEM TO BE SOLVED: To provide a method and an apparatus for analyzing the earthquake resisting strength of a piping network capable of obtaining the earthquake resisting strength of the piping network, etc., as theoretically concrete and accurate data not by a theory of probability but by a technique of structural mechanics or material mechanics and executing simple analytical techniques in a short time. SOLUTION: An earthquake resisting strength analyzing part 200 regards total three unit elements of the piping, an rectilinear element and two boundary elements of both ends of the rectilinear element, as constituting one base element, makes the individual base elements of the piping network discrete, and analyzes the individual base elements on at least one type of displacement, distortion, and stress which occur due to vibrations and external forces caused by earthquakes. At this time, corresponding types of data are read and used for data on the deformation characteristics of the boundary elements from among data previously obtained by an infinite element method, formed into a database, and stored in a boundary element database storage part 100.
