摘要
笔者通过采用三维有限元对新疆某水电站厂房整体结构进行动力计算,分析了结构自振频率和振幅(机组振动和地震)对结构的影响,提出厂房结构布置建议,并在施工图设计中对结构布置进行调整。计算分析结果验证了结构布置的合理性、可靠性,为静力计算及确定主要构件的断面设计和配筋设计提供依据。
The influence of natural vibration frequency and amplitude( unit vibration and earthquake) on the structure is analyzed by using three-dimensional finite element method to calculate the overall structure of a hydropower house in Xinjiang. Suggestions for the layout of the powerhouse structure are put forward, and the structural layout is adjusted in the design of construction drawing. The calculation and analysis results verify the rationality and reliability of structural arrangement, and provide the basis for static calculation and section design and reinforcement design of main components.
