Specifies the number of the starting node of a group of restraints at which the spectrum load is applied for independent support motion analysis (ISM). The spectrum is applied to all restraint nodes in the group between Start Node and Stop Node in steps of Increment. The range of nodes must include at least one node in the piping system.

The component of an independent support shock applies only to a group of support points. For example, different shock spectra are generated for rack level piping and for ground level piping. The rack supports are subject to one shock excitation, influenced by the rack’s response to the earthquake. The ground level supports are subject to a different shock excitation, not influenced by the rack. One node range is used to define the rack support shock contributions, and another is used to define the ground support shock contributions.

This option is only available when Earthquake (spectrum) is selected for Analysis Type.
