A practical calculation method is presented from the viewpoint of the aseismic design convenience for liquid storage tanks and various piping systems established in industrial facilities such as petrochemical plant complexes. Utilizing the results obtained in the previous studies, correlation effects appearing among different loadings and response reduction effects due to structural nonlinearities such as gaps and friction between piping and a supporting structure can be represented by a numerical diagram prepared for various system parameters. According to the calculation based on this diagram, sophisticated seismic response calculation procedures can be remarkably simplified. Several examples are demonstrated.
