摘　　要：介绍了时程分析概念及计算步骤,了解了框架结构动力分析的常用方法.以七层框架结构为研究对象,将阻尼支座布置在不同结构楼层位置处,应用SAP 2000软件分别计算其结构的动力时程,比较结构的层间剪力和层间位移等在地震作用下的反应参数.分析对比这些反应参数产生的原因和隔震结构受力机理,结果表明,结构中设置隔震支座后能有效地减少结构的地震作用反应,其中基础隔震的布置比较合理.The common methods of d yn amic analysis of f ram e s t ru c tu re s are s tu d ie d f rom the concept and calculation procedure of t ime history analysis are in t ro d u c e d .T h e object of s tu d y is the Seven-story f ram e structure,the damped bearings are arranged on the d i f fe re n t f lo o rs o f the s t ru c tu re .

T h e n , were c om -pared Seismic response parameters such as in te r lam in a r shear and displacement were comp a re d . T h e mechanism of stress causes and isolat ion s t ru c tu re comparat ive analysis of these react ion parameters can be generated.A conclusion is drawn that isolated s t ru c tu re can e f fe c t ive ly reduce the seismic response, and the base isolation is more reasonable under d amp in g s u p p o r t in d i f fe re n t lo ca t io n s .
