CAESAR II Version

(Available for: Spectrum)

Specifies the method for combining the spatial contributions of the shocks in a single spectrum load case. Select SRSS for a square root of the sum of the squares combination method. Select ABS for an absolute combination method.

This option is only used for spectrum runs with more than a single excitation direction. Because directional forces are usually combined vectorially, SRSS is usually the best selection. ABS is provided for additional conservatism.

Because all time history combinations are done algebraically (in-phase) this option has no effect on time history results.
