We had already proposed general multi-mass shear models for super high-rise RC buildings using averaged properties of nonlinear parameters. This study investigates fluctuation of seismic response characteristics considering variation of nonlinear parameters, i.e., shear capacity and deformation of tri-linear skeleton points, based on statistical analysis of the 78 models used in the past structural design. Variation of natural period and cracking points has more influences on averaged height-wise distribution of maximum inter-story drift angles than that of yielding points.
