Response Spectrum analysis for OpenSees<\/strong>
\nTo perform a Response Spectrum analysis based on modal results, use the following command:<\/p>\n

dynModal $numModes $spectrum $patternID $comb $csi $dir1 $dir2 $dir3<\/em><\/p>\n

where $numModes<\/em> is the number of modes the user wants to combine, $spectrum<\/em> is the name of the file containing the spectrum points, $patternID<\/em> is the ID to be given to the load patterns created internally to perform the required linear static analyses, $comb<\/em> let the user choose whether the SRSS or CQC method should be used, $csi<\/em> is the damping ratio which is used to calculate the correlation coefficients needed when performing CQC.
\nThe last three parameters ($dir1<\/em>, $dir2<\/em>, $dir3<\/em>), which may assume a value of 0 or 1, are needed to specify the directions associated with the spectrum.<\/p>\n
