1) Der orthogonale Kombinationsfaktor ist standardmäßig auf 0.3 (30%) eingestellt. This value can be changed by going to Edit Parameters of Edition in the Load Cases & Combinations (Image 01)
2) Erstellen Sie im Register "Lastfälle" die Erdbebenlastfälle in X- und Y-Richtung mit Qe als "Einwirkungskategorie". Aktivieren Sie die 'Zusätzlichen Einstellungen | Consider X and Y independently' option.
Under the Additional Settings tab, activate "Direction X" option for the "Seismic X" load case. For the "Seismic Y" load case, activate "Direction Y".
After doing so, activate the 'Consider load case for orthogonal combination' option. The orthogonal direction from the drop-down menu is automatically selected for both LCs (Image 02). The Load Combinations generated according to the ASCE 7 will include all variations of the 100/30 rule.
3) The generated COs including the orthogonal combination factor are listed in the Load Combinations tab (Image 03)
