| 摘 要： | 采用数值模拟方法,对新广州火车站雨棚挡雨板结构进行了方案优化设计研究,以减小结构风荷载。数值模拟显示,挡雨板的位置若进行微调,承受的风荷载可显著降低,从而在不增加任何投入的前提下,提高结构的抗风安全性。研究还表明,通过建立适当的数值风洞模型,不仅可获得可信的结果,而且可从流动本身进行机理解释,数值模拟方法是进行此类结构...

| Abstract: | The optimization design of the canopy of new Guangzhou Railway Station was numerically conducted from the viewpoint of reducing its wind loads.Numerical results show that the wind loads could be significantly reduced only if the arrangement of the serials of baffles is slightly adjusted.Therefore,the wind-resistant safety of this structure could be improved without any additional measures.Through the research,it concludes that not only the reliable results could be obtained,but also the mechanism behind the... |
