| 摘 要： | 以某后端开口的落地式拱形体育场看台挑篷为背景.采用计算流体力学(CFD)软件Fluent得到该结构的风压力、风压系数分布以及结构附近的流场分布.对风压和流场分布进行r详细的描述和讨论,发现这种挑篷形式与一般悬挑式体育场看台挑篷类似,最不利工况为风从前缘正面吹来对屋盖造成的强大上吸力.在实际设计中挑篷体埠!系数可分别取为...

| Abstract: | The distribution of wind pressure and wind-pressure coefficient on an arch roof covering the stand of a palaestra was studied by applying the CFD software Fluent.The fluid field condition around the roof was also studied.The arch roof has a gap at its back and links with ground.It shows that the most unfavorable load case is the arch roof suffering wind load in its front face under which the roof suffers a powerful upward load,and the phenomenon is similar with the traditional cantilever roof.Shape coeffici... |
