In modal analysis cases, Mode Number, Convergence Value and Iteration Number information are given for modal analysis. When you analyze on any system, the program will automatically create a modal analysis case for modal analysis. When the "bi-loading calculation methodSeperate analysis for basements" option is selected from the analysis settings, 10 modal analyzes are defined for buildings containing basements. 4 of these modal analysis cases are modal analysis cases obtained by shifting the center of mass for the superstructure by +-5% in the X and Y directions, respectively (Modal E1, Modal E2, Modal E3, Modal E4). The other 4 modal analysis cases are modal analysis cases (Modal BE1, Modal BE2, Modal BE3, Modal BE4) obtained by considering the basement floors of the basement building and shifting the center of mass +-5% in the X and Y directions. Modal' is the modal analysis case defined without the effect of eccentricity for the superstructure and Modal-B' is the modal analysis case defined without the effect of eccentricity by considering the basement masses of the basement building.
