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
