INCOH Command

INCOH,<gammax>,<gammay>,<gammmaZ>,<vs>,<ngp>,<ipr>,<nmodes>,<met>,<HSeed>,<VSeed>,<RandPhz>

defines the following incoherence analysis options for ACS SASSI HOUSE module:

• <gammax>- coherence parameter for x direction
• <gammay>- coherence parameter for y direction
• <gammaz>- coherence parameter for z direction
• <alpha>- directionality parameter (for Abrahamson model only, use mean shear wave velocity for Luco-Wong model)
• <ngp>- number of mesh points per each embedment level
• <ipr>- print code for coherence functions
  • 0 - no print
  • 1 - print
• <nmodes>- number of modes used for quadratic superposition (use -<nmode> for a single mode)
• <met>- Flag for use of metric Units
  • 0 – standard
  • 1 – metric
• Hseed- Horizontal Seed
• Vseed - Vertical Seed
• RandPhz- Random Phase Angle in degrees

Note: This instruction is provided for input files. To set the incoherence analysis options for the ACS SASSI HOUSE module from the ACS SASSI PREP or SASSI User Interface, use the Options / Analysis menu option.
