[摘要] 復(fù)雜結(jié)構(gòu)、超限高層結(jié)構(gòu)在實(shí)際工程設(shè)計(jì)時(shí)需要進(jìn)行中震設(shè)計(jì)和驗(yàn)算。本文從抗震規(guī)范中小震、中震和大震的概念入手，說明了中震設(shè)計(jì)和驗(yàn)算的工程概念和方法，提出了在現(xiàn)行規(guī)范和設(shè)計(jì)條件下，在實(shí)際工程中進(jìn)行中震設(shè)計(jì)的設(shè)計(jì)要點(diǎn)和應(yīng)注意的一些問題。

Abstract: It is necessary that complicated structures are analyzed and checked under seismic intensity(medium earthquake). Based on the concept of frequent seismic intensity (low earthquake), seismic fortification intensity (medium earthquake) and very rare seismic fortification intensity (great earthquake), this paper suggests some ideas about structural design under medium earthquake and  proposes some methods of structural design under medium earthquake in the condition of actual code and design methodS.
Keywords: complicated structure; unregulated structure; elasticity level under medium earthquake; un-yielding level under medium earthquake; parameters of ground motion
