This paper presents the wind-induced responses and wind resistant design method of arch-supported membrane structure. Series of rigid model wind tunnel tests are carried out to record wind pressure data on the roof surface of experimental models. Random vibration time history analysis is employed to get wind-induced responses. Geometric nonlinearity is taken into account in dynamic analysis. Effects of different factors such as wind velocity, wind direction, arch span, rise-span ratio, and membrane prestress on peak wind-induced responses are presented meticulously. Displacement, membrane stress, internal force of cable and abutment reaction are analyzed to study the peak responses of structure. This study considers the influence of boundary wall by conducting wind tunnel tests on both enclosed and open models. Results show that peak responses increase significantly as wind velocity and/or arch span increase. The performance of membrane structures can be enhanced by increasing membrane prestress, but the effect is quite small. Similarly, responses increase with rise-span ratio, but the rate of increment is not constant. Effect of the boundary wall depends significantly on wind direction and rise-span ratio. Additionally, this paper proposes the concept of equivalent static design method based on gust loading factor and nonlinear adjustment factor.

提出了拱支撑膜结构的风致响应及抗风设计方法。进行了一系列的刚性模型风洞测试，以将风压数据记录在实验模型的屋顶表面上。采用随机振动时程分析来获得风致响应。动力学分析中考虑了几何非线性。精心介绍了风速，风向，拱跨度，升跨比和膜片预应力等不同因素对峰值风致响应的影响。分析了位移，膜应力，电缆的内力和基台反应，以研究结构的峰值响应。本研究通过对封闭模型和开放模型进行风洞试验来考虑边界墙的影响。结果表明，峰值响应随着风速和/或拱跨的增加而显着增加。膜结构的性能可以通过增加膜的预应力来增强，但效果很小。类似地，响应随跨度比的增加而增加，但是增加的速率不是恒定的。边界墙的影响在很大程度上取决于风向和升跨比。另外，本文提出了基于阵风荷载因子和非线性调节因子的等效静力设计方法的概念。边界墙的影响在很大程度上取决于风向和升跨比。另外，本文提出了基于阵风荷载因子和非线性调节因子的等效静力设计方法的概念。边界墙的影响在很大程度上取决于风向和升跨比。另外，本文提出了基于阵风荷载因子和非线性调节因子的等效静力设计方法的概念。
