Abstract
In this paper different approaches in seismic design are investigated. Commonly used static analysis is compared with two different cases of harmonic analysis. The static analysis is based on a design response spectra. In the harmonic analysis, case 1, the loading is in the form of acceleration applied to the mass, for case 2, the loading is in the form of applied displacements to the supports. A typical expansion pipe unit is analysed with all three methods. It is shown that standard procedures can lead to a conservative design and prevent the optimization of the results. An optimum design can be obtained by using supports with adequate damping and stiffness, and hence, the loading on the piping system can be minimized.
