Due to the features of light weight, high flexibility, and slight damping, large-scale spatial structures are very sensitive to wind load. Thus, special attention must be paid to wind effect on large-scale spatial structures. A wind pressure field measurement was carried out to characterize the actual wind pressure of a large-span spatial structure. Meanwhile, it is also intended to provide reliable full-scale measurements for verification of wind tunnel test results widely used in the design and construction of structure. In this study, both wind tunnel test and field measurement are utilized to investigate the properties of the wind pressure acting on a typical large-scale spatial structure. Specifically, wind pressure coefficients, spatial distribution, probability density distribution (PDF), non-Gaussian characteristics, and power spectral density (PSD) are fully compared and discussed based on the results of the wind tunnel test and long-term field measurement. The comparison results show that generally the results of the wind tunnel test have good agreement with those of the field measurement. In the meanwhile, the discrepancies between them are also observed. This study aims to fully investigate the wind effects on large-scale spatial structure and enhance the understanding of wind loads.

由于重量轻，柔性高，阻尼小等特点，大型空间结构对风荷载非常敏感。因此，必须特别注意风对大型空间结构的影响。进行风压场测量以表征大跨度空间结构的实际风压。同时，它也旨在提供可靠的全面测量，以验证在结构设计和施工中广泛使用的风洞测试结果。在这项研究中，利用风洞测试和现场测量来研究作用于典型大型空间结构上的风压特性。具体而言，风压系数，空间分布，概率密度分布（PDF），非高斯特性，根据风洞测试和长期现场测量的结果，对功率谱密度（PSD）和功率谱密度（PSD）进行了充分比较和讨论。比较结果表明，风洞试验的结果与现场测量结果基本吻合。同时，还观察到它们之间的差异。这项研究旨在全面研究风对大型空间结构的影响，并增强对风荷载的了解。
