At present

structure design method of gymnasiums in China calculates the internal force and deformation of structure by elastic design under minor earthquake. The method considers major earthquakes by various seismic technical measures

but not verify seismic performance under the action of moderate and major earthquakes. In this paper

based on the minor earthquake elastic design model of a single-storey gymnasiums with attached frame

the moderate earthquake non-yielding design and moderate earthquake elastic design were carried out

and the variation of reinforcement and the difference of seismic performance were compared caused by the different performance objectives of the three design methods. The research shows that the reinforcement amount of structure with the gymnasiums was increased based on the design of moderate earthquake performance

compared to the minor earthquake elastic design of that. The former can better guarantee the fortification requirements of mendable under moderate earthquakes and no collapse under major earthquakes.
