摘要
体育场看台挑篷是典型的风敏感结构。气动弹性模型风洞试验是研究其风振响应的有效方法,但由于挑篷结构质量轻、刚度小,气弹模型设计和制作均很困难,所以目前在实际工程抗风研究中很少应用。本文以一实际体育场主看台挑篷为对象,研究了这类轻柔结构的气弹模型的设计和制作方法,并通过风洞试验进一步了解体育场主看台挑篷的风振响应特性,获得了这类结构的风致响应的基本特征。
Grandstand cantilevered roofs of large stadiums have become a kind of typical wind-sensitive structures due to their flexible and light features. Also due to the features, the design and manufacture of the aeroelastic model are difficult although the kind of models are effective to investigate responses of the structures under strong wind actions, and thus has been seldom used in practical application. A real grandstand cantilevered roof of large stadium is taken as the prototype of the present study. The aeroelastic model of the roof structure is designed and manufactured, and the wind tunnel test is then carried out. The test results are further compared with the computed results which have also been made by the authors to verify the reliability of the model and the test results. Some important conclusions are finally summarized.
