result nd analyze-

-modal mass participaton for first 3 modes dominates at least65%(archieved for x axis only)

-mode1 and mode 2 differs by 10%(archieved)

-principal modes be greater than torsional mode(archieved)

-inter storey drift ratio limited to 0.004(archieved)

-axial stress in column and shear wall(archieved)

-base shear share between shear walls and columns(not dual system)
