［摘要］超限高層的抗震等級往往取為一級或特一級。較高抗震等級結(jié)構(gòu)的內(nèi)力調(diào)整系數(shù)較大，導(dǎo)致小震彈性設(shè)計內(nèi)力放大較多，甚至超過中震的內(nèi)力設(shè)計值。通過詳細的分析，給出小震設(shè)計內(nèi)力與中震設(shè)計內(nèi)力的對比，并提出相應(yīng)的設(shè)計建議，為實現(xiàn)性能設(shè)計提供參考。

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
