EXPERIMENTAL MODAL ANALYSIS FOR SHANGHAI KEWEI BUILDING STRUCTURE
-
摘要: 结合上海科维大厦结构动力模态测试分析的工程实例,针对测试数据的现场布点、采集、时域到频域的转换过程进行简要阐述。对测试数据中判别出的结构低阶自振频率与有限元计算结果进行对比,分析误差的合理原因。重点就计算模型中需要修正的参数进行探讨,以供类似的工程设计参考。Abstract: The experimental modal analysis has been adopted in Shanghai Kewei Building which is an ultra -code high -risebuilding. This paper introduces the designed engineering project as a special case to find the critical path method anddiscusses the main features in the anti-seismic design model.Analysis of the tested data and calculated data by finiteelement software are decided to find the reasonable errors and the experience from this project can be used for reference.
