| 摘 要： | 超限高层的抗震等级往往取为一级或特一级。较高抗震等级结构的内力调整系数较大,导致小震弹性设计内力放大较多,甚至超过中震的内力设计值。通过详细的分析,给出小震设计内力与中震设计内力的对比,并提出相应的设计建议,为实现性能设计提供参考。

| Abstract: | Anti-seismic grade of super high-rise buildings is always grade I or extra grade I.Higher anti-seismic grade leads bigger adjustment coefficient of internal force,which makes design values of internal force under small earthquake be even more than those under medium earthquake.Comparative analysis of internal force under different seismic fortification levels was done and design proposal in seismic design was given,which can give reference for realizing performance-based seismic design. |

| Keywords: | super high-rise building elastic design under medium earthquake non-yielding design under medium earthquake performance-based seismic design |
