Abstract The utilization of large-span membrane structures as airport terminals has attracted considerable attention due to excellent building aesthetics, reasonable structural behavior and multi-functional applications. Safety and serviceability of such structures are strongly related to temperature effects in comparisons with steel/aluminum structures since temperature can accelerate material creep strain and deteriorate structural behavior. One alternative method to reduce temperature effects is the incorporation of aerogel materials between two membrane layers. This paper thus focuses on temperature effects of a newly-built aerogel-membrane airport terminal and utilizes experimental results to assess corresponding building performance. The aerogel-membrane airport terminal is designed with wind loads of 0.4 kN/m2, snow loads of 0.7 kN/m2 and earthquake magnitude of 7 in accordance with the requirements of building standards and codes. The aerogel-membrane roof is composed of an outer membrane layer and an inner composite membrane layer integrated aerogel material mats. The surface temperature gradients with respect to outer membrane layer, inner membrane layer and indoor air are identified and quantified. The quantified temperature can be used for thermal-structural analysis and building performance improvement in the design process. The calculated thermal performance indexes mean a hot environment in the inner airport space. A further comparative analysis with a two-layer membrane stadium demonstrates that aerogel materials can reduce temperature effects significantly and ensure structural safety. Therefore, the effects of aerogel on the improvement of structural behavior and building performance of a new membrane airport have been validated with experimental results and comparisons.

某大跨度气凝胶膜机场航站楼建筑性能监测与分析

摘要 大跨度膜结构作为机场航站楼的应用，以其优异的建筑美观性、合理的结构行为和多功能应用而受到广泛关注。与钢/铝结构相比，这种结构的安全性和适用性与温度效应密切相关，因为温度会加速材料蠕变应变并使结构性能恶化。减少温度影响的一种替代方法是在两个膜层之间加入气凝胶材料。因此，本文重点研究新建气凝胶膜机场航站楼的温度影响，并利用实验结果评估相应的建筑性能。气凝胶膜机场航站楼的设计风荷载为 0.4 kN/m2，雪荷载为 0。7 kN/m2 和 7 级地震，符合建筑标准和规范的要求。气凝胶膜屋顶由外膜层和内复合膜层一体式气凝胶材料垫组成。外膜层、内膜层和室内空气的表面温度梯度被识别和量化。量化的温度可用于设计过程中的热结构分析和建筑性能改进。计算出的热性能指标是指机场内部空间的热环境。与两层膜体育场的进一步对比分析表明，气凝胶材料可以显着降低温度影响并确保结构安全。所以，
