Research of ground seismic design response spectrum on a super high rise building

Ground seismic design response spectrum is an important basis for seismic design of super high rise building,which is related with the structural safety and cost.A case of super high rise building design was introduced in the paper,in which the influences of different exceeding probabilities on ground seismic design response spectrum and contribution of seismic hazard of horizontal peak acceleration are analyzed.And ground seismic design response spectrum was compared with natural seismic spectrum,which proved the reliability of ground seismic design response spectrum.The results showed that large earthquake of far-field should be considered besides earthquake of near-field in seismic design of super high rise building.The natural seismic spectrum derived by the method introduced in this paper could be the basis of structural checking calculation,which enhanced structural safety.
