WebMay 9, 2024 · The CQC method has been shown to be better than the other methods, like SRSS and NRL, which were shown to give poor results in certain cases when the system modes are closely spaced. The method was developed originally with quantities of interest based on relative displacement; however, it has been used with other response spectra, … WebIn the i'th step of the thrust analysis with the ARSA method, the structural responses calculated separately for the (X) and (Y) earthquake directions, i.e. typical displacement, plastic deformation or internal force values r x (i) and r y (i ) is expressed with.. Full Quadratic Combination (TKB or CQC) rule is explained in Annex 4B.2.4 of TBDY Section.
WebThe modal response is determined by means of the following formula. where: n - Number of modes e ij - Correlation coefficients R i , R j - Spectral response to the modes i and j The following types of quadratic combinations are available in the program. SRSS Method For SRSS method, the correlation coefficients equal: eij = 1 for i=j, eij = 0 for i≠j, thus: CQC … WebSep 1, 2011 · The CQC method degenerates into the SRSS method for systems with well-spaced natural frequencies.
