针对影响大跨屋盖结构风荷载分布特征的诸多复杂因素,并结合深圳会议展览中心风洞试验项目的研究,本文应用模糊神经网络方法,成功地预测了大跨屋盖结构的风压分布特性。研究结果表明,采用该方法可以综合考虑各种因素的影响,并十分有效、简捷地处理常规方法难以解决的问题,进一步的应用表明这种方法可以用于其它类型建筑物风洞试验的数据处理和风压分布预测。
In view of many complicated factors that affect the wind load distribution characteristics of long-span roof structures and the wind tunnel test project in Shenzhen Convention and Exhibition Center, this paper applies the fuzzy neural network method to predict the wind pressure distribution characteristics of long-span roof structures . The results show that this method can comprehensively consider the impact of various factors and is very effective and simple to deal with the problems that conventional methods can not solve. Further application shows that this method can be applied to the data processing of wind tunnel tests in other types of buildings And wind pressure distribution forecast.
