中文摘要：
本文基于各国抗震设计规范对自振周期经验公式进行了对比分析,绘制了自振周期与高度的变化曲线。对结构弹塑性阶段自振周期增长,通过等效线性化方法对自振周期进行调整,绘制了延性系数与弹塑性周期调整系数的关系曲线。最后,建立了在不同延性系数下结构弹塑性周期与高度、宽度的函数关系。
英文摘要：
Based on many countries＇s seismic codes,fundamental vibration period was analyzed,and the carve about vibration period and height was drawed.For the increase of inelastic structural vibration period,the equivalent linearization method was adopted to adjust vibration period,and the carve about ductility coefficient and inelastic period adjustment factor was drawed.Finally,the function about inelastic structural vibration period and height、width under different ductility coefficient was built in this paper.
