# UCORR

 User subroutine to define cross-correlation properties for random response loading. User subroutine UCORR: can be used to define the coefficients for the cross-correlation matrix in a random response analysis; will be called once for the combination of any two degrees of freedom with nonzero prescribed loads for each load case specified as a concentrated or distributed load or once for the combination of any two excitation directions specified as a base motion; allows correlation coefficients to be defined as a function of nodal coordinates; and ignores any data specified outside the user subroutine for the associated cross-correlation matrix. The following topics are discussed:
