摘要
对深圳愿望塔模型结构进行了在7度小、中、大震作用下的振动台试验分析、动力时程数值分析、Pushover数值分析,并将地震反应结果进行对比分析,对深圳愿望塔进行深入的抗震性能分析,通过对比分析验证Pushover分析的可靠性。从各种分析曲线形状可知,三种分析方法的分析曲线的总体形状是相近的,说明从宏观上看,用此三种分析方法分别对结构进行抗震性能分析所得出的相应分析结果基本一致;另外,Pushover数值分析的结果与其他两者相比,较为保守。
A shaking table test of Shenzhen Willing Tower is introduced. Then its dynamic time-history numerical analysis, Pushover numerical analysis are compared. By these curves, we can see that the overall curve shape of the three analysis methods are close, so general speaking, the corresponding seismic behavior analysis results using these three methods are consistent generally. In addition, the results of Pushover analysis are more conservative than the other two.
