结果表明，混凝土芯筒的剪力墙屈服后，其内置的延性加强构件(钢管柱)对结构的防倒塌有显著的作用。
It is found that the ductile strengthen member (concrete fill steel tube) play an important role to prevent the structure from collapse after the shear walls partially yield.
地震力降低系数对设防烈度地震作用的整体降低实际上决定了结构的屈服水准和对结构延性需求的大小。
Lower coefficient of earthquake seismic intensity of the security role in the decision to lower the overall structure of the yield of standard size and structure of the extensive demand.
引入结构屈服水平系数，建立了结构的延性需求谱，使地震动的幅值特性和频谱特性可以分开考虑。
By introducing the yielding level factor and constructing the ductility demand spectrum, the characteristic of peak values and frequency contents of ground motions are considered separately.
