| 摘 要： | 分别在A类地貌和B类地貌中测得某核电常规岛厂房的刚性模型表面风压风洞试验数据。用频域方法计算了厂房屋盖风致动力响应。计算结果显示结构动态位移响应在不同地貌中差别较小。且正面迎风时结构风致动态位移均方根响应比斜向迎风时要小。分析了不同风向角下结构表面风压谱密度的分布,结构正面迎风时,结构表面风压谱密度函数能量主要分布在低频段;当风沿斜向作用时,结构表面风压谱密度函数能量主要分布在高频段。风压谱密度函数谱峰对应的折算频率与结构振型对应的自振折算频率一致时,结构风致动力响应将会增大。

| Abstract: | The surface pressure measurements of a nuclear power factory building model were carried out under A and B categories of terrains in wind tunnel.Based on the wind tunnel data,the wind induced responses of the building was evaluated by the method of frequency domain.The calculated results showed that the differences of the RMS displacements in two terrains were minor.When the structure was under skew flow actions,the responses were larger than the case in right wind angle.Investigation on the distribution of... |
