【摘要】 作用在薄膜结构上的风荷载,除与气流本身的特性有关外,还与结构在风荷载作用下的位移、速度、加速度等有关。薄膜结构与风环境之间存在着较强的流固耦合作用,并且这种耦合作用往往对薄膜结构的振动起控制作用。将两者的耦合作用分为静力耦合作用和动力耦合作用,并主要针对静力耦合作用所涉及的几个因素运用解析公式的说明方法进行了初步分析总结,为进一步的风致动力响应研究和风洞试验研究奠定了理论基础。更多还原

【Abstract】 The wind pressure acting on a membrane structure is relative to the structure displacement,velocity and acceleration as well as the characteristics of airflow itself.There is an intense interaction between wind and fabric structures,which is a critical factor for the dynamic behavior of fabric structures.The interaction is grouped as the static interaction and the dynamic interaction and the relevant factors of static interaction are analyzed and summarized preliminarily by analysis formula.Results from this study provides theoretical foundation for the future wind-induced response and wind tunnel test.更多还原
