Should the modal spectral analysis be selected to consider the effect of earthquake, the maximum response of the structure in the seismic load is estimated by combining the results of the modes of vibration by means of the Complete Quadratic Combination (CQC). In versions prior to 2026.a, it was only possible to consult the forces, reactions, displacements, etc. of the seismic loadcase by mode. This is now also possible for the CQC modal combination.
