摘要
通过对完全相同的装配式高层剪力墙结构和现浇结构在环境激励下现场实测随机振动分析,所获得的自振频率和振型等模态信息可有助于装配式结构动力性能及抗震安全分析。结合同条件装配式结构和现浇式结构的现场对比模态测试,进一步按照YJK、MIDASGen两种有限元软件进行相关分析,同时与不同国家和地区规范理论计算值进行比较,掌握了理论和实测自振周期等的差异,获得了对两种结构模态方面的新认识。
Through the field random vibration analysis of the same prefabricated high-rise shear wall structure and cast-in-place structure under environmental excitation,the obtained modal information such as natural frequency and mode shape can contribute to the dynamic performance and seismic resistance of the prefabricated structure Security analysis.Combined with the on-site comparative modal test of the same-condition assembled structure and cast-in-place structure,the relevant analysis was further carried out in accordance with the two finite element software YJK and MIDAS Gen.At the same time,it was compared with the theoretical calculation values of different countries and regions.The difference in the measured natural vibration period,etc.,gained a new understanding of the two structural modes.
