Abstract

The design of tensile membrane structures requires the determination of the wind induced pressure distribution on their unique anticlastic surface. Design codes, however, only provide pressure coefficients for more conventional wall and roof shapes. The current paper presents the wind tunnel test and load analysis of a common arch-supported tensile roof shape by wind tunnel tests on a rigid small-scale model. At wind directions parallel or almost parallel to the arches, trip wires were applied to model high (supercritical) Re-number flow. Besides the detailed experimental methodology and conditions description, the evaluated results are introduced, including pressure coefficient distributions and the membrane forces for various wind directions. Based on the experimental pressure coefficients, simplified pressure coefficient maps were also determined for each roof zone for six wind directions for design purposes.

多跨拱支张膜结构的风分析

拉伸膜结构的设计需要确定其独特的抗裂表面上的风致压力分布。然而，设计规范只提供了更传统的墙壁和屋顶形状的压力系数。本文采用刚性小模型风洞试验方法，对一种常见的拱支受拉屋面进行了风洞试验和荷载分析。在与拱平行或几乎平行的风向下，用绊网模拟高（超临界）复数流。除了详细的实验方法和条件描述外，还介绍了评估结果，包括不同风向下的压力系数分布和膜力。基于实验压力系数，确定了简化后的6个风向下各顶板区域的压力系数图，用于设计目的。

期刊介绍： The objective of the journal is to provide a means for the publication and interchange of information, on an international basis, on all those aspects of wind engineering that are included in the activities of the International Association for Wind Engineering http://www.iawe.org/. These are: social and economic impact of wind effects; wind characteristics and structure, local wind environments, wind loads and structural response, diffusion, pollutant dispersion and matter transport, wind effects on building heat loss and ventilation, wind effects on transport systems, aerodynamic aspects of wind energy generation, and codification of wind effects. Papers on these subjects describing full-scale measurements, wind-tunnel simulation studies, computational or theoretical methods are published, as well as papers dealing with the development of techniques and apparatus for wind engineering experiments.
