Reduction rates under 53 sets of seismic excitations. (a) Fourier amplitude spectrum of the 23rd and the 38th seismic excitations and the operating range of the structure with CBDs. (b) Comparison of interstory drift reduction rate between the 23rd and the 38th seismic excitations. (c) Response spectrum comparison between the 23rd and the 38th seismic excitations.
