A set of structural models are generated associated with variation of the strength of frame determined from the base shear coefficient in the structural design. A series of dynamic response analyses have been carried out. Through the analyses, the greater is the strength of frame specified, the greater fluctuation of axial force within columns is obtained, which is, however, not increased in a direct proportion to the prescribed strength of frame and remains constant when the strength of frame is taken moderately great. In conclusion, in the seismic design of high-rise reinforced concrete buildings with the concept of moment-resisting ductile frame, it is recommended that a sufficient level of strength of frame should be ensured not generating large deflection responses and not producing excessively large inelastic hinge rotations at the ends of beam. When the strength of frame is taken moderately great, the fluctuation of axial forces observed for columns within the building will not be yielded excessively great but will remain invariant with moderate fluctuation, not being increased extremely as speculated from the results of a static analysis.
