| 摘 要： | 在等效单自由度体系地震反应目标位移计算方法的基础上,提出考虑高振型影响的结构推覆分析目标位移计算方法.利用该方法和其他常用推覆分析方法,进行不同层数的钢筋混凝土规则框架结构推覆分析,并与地震反应非线性时程分析结果进行比较和分析.结果表明,所提出的改进方法能够较好地考虑结构地震反应中高阶振型的影响.

| Abstract: | An improved method for calculating the target displacement of pushover analysis is proposed based on equivalent single-degree-of-freedom system,which considers the contribution of the higher modes in seismic response.The pushover analysis of RC(reinforced concrete) regular frame structures with 4,8,and 12 storeys are carried out by this improved method,and other common methods.Comparing the results of this improved method with the results of other pushover analysis methods and nonlinear time history analysis method,it's shown that this improved method can properly consider the contribution of the higher modes in seismic response of the regular frame structure. |

| Keywords: | seismic response target displacement higher modes pushover analysis dynamic time history analysis |
