考虑支座性能弦支穹顶空间结构静动力性能分析

摘要

Considering actual performance of elastic ball steel bearing,the single suspen-dome model and the integral structure analysis model of Qinyang Gymnasium were established.Analyses of the two models were carried out and the static and dynamic responses of the structures were compared with the analysis results of the corresponding ideal fulcrum bearing suspen-dome single model.Error analysis of the ideal fulcrum bearing suspen-dome single model was conducted.This study provides a reference for this type of suspen-dome structure.%以沁阳体育馆为工程背景,建立考虑支座实际工作性能的弦支穹顶屋盖结构单体模型、考虑支座实际工作性能的整体模型.与理想支座连接的简化单体模型进行静动力响应对比分析.对简化单体模型计算结果进行误差分析,为这一类弦支穹顶结构的设计提供参考.
