C ompared the results of structural period, displacement and internal forces of mode 1 with mode 3, we can know that the hypo - frame can increase the lateral stiffness of the mega steel - frame structures, decrease lateral - deformation of the structures, especially decrease the maximum inter - storey displacement obviously, and get the internal forces and deformation of the whole structure more uniform. from the analysis results, it can be found that the maximum axial force gets less with hypo - frame than without it, and the maximum shear force and bending moment get more with hypo - frame than without it. thus it can be seen that the mainframe can be an independent structure system by itself, but the cooperation of main and hypo frame should be considered for conducting the entire analysis and design, otherwise the mega structure can be unsafe, in addition, from the comparing analysis, it can be found that the shear force and bending moment of inside - row columns are increased much more than those of outside - row ones in a mega column
