Behavior Of High And Intermediate Frequency Modes Of Structures Subjected To Harmonic Excitation,e modal responses of the structures subjected to harmonic excitation are generally combined using square root of sum of squares (SRSS) rule for well separated modes. The combination of modal response s using SRSS will results in erroneous results for even well separated modes, if the high frequency
