摘要
通过总结相关研究成果和相关设计规范要求,结合常用结构设计软件的阻尼比计算功能,介绍了天津网球中心比赛场项目结构应变能阻尼比的计算应用和等效综合阻尼比的计算方法;并对不同阻尼比下的计算结果差异进行比对,阐明阻尼比对结构分析结果的影响。
The research results and current codes which calculate the damping ratio on non-classic damping system were summarized,which using damping ratio calculation function in popular structural design software.It introduced the calculating method of structural strain energy and the equivalent damping ratio by the example of Tianjin Tennis Center.And then with comparing the calculated results on different damping ratios,it clarified the impact on structural analysis.
