Selection of earthquake waves in elastic time-history dynamic analysis
In elastic time-history dynamic analysis for building structures, both easy to operate and rationality in waves selec tion are both important. By using to the results of elastic time-history dynamic analysis for structural design of a Shanghai su perhigh building, the wave-selection with engineering significance is discussed. The study shows that for the bending moment or the shear force of base, structure responses of three-direction-input are smaller than the response of one-direction-input.When using small sample size of earthquake waves. The increase in the number of artificial waves can reduce the overall dispersion of earthquake waves.
