摘要

将空间核筒悬挂结构简化为考虑节点转动影响的串并联多质点系平面模型,建立其振动微分方程。编制MATLAB程序,得到结构水平和竖向自振特性,并用时程分析计算水平和竖向耦合地震波激励下结构的动力响应,与单维地震波激励相比较,结构部分构件响应有明显差异。通过对计算结果的分析,可以更全面地掌握核筒悬挂结构的抗震性能,对悬挂结构进一步的抗震研究和设计具有参考价值。
The core-tube suspended structural had been simplified to plane model by using series-parallel-connection model considering joint rotation and vibration equation was established.Vibration performance of the structure was figured out by MATALB program and time-history analysis method was used to analyse dynamic response of the structure under vertical and horizontal seismic coupling excitation.By comparison with single-dimension seismic excitation, the response of some components have a significant difference.The conclusion help the mastery of core-tube suspended structure vibration characteristic and can be refered for the further research and design.
