封闭式大跨度建筑的吊顶性能，如体育场、机场航站楼和游泳池，与安全要求、工作适用性和能源需求有关。传统的大跨度建筑石膏板和/或铝板吊顶在地震作用下存在潜在危险，在正常工作条件下耗能大。为了确保安全性能和管理能源性能，考虑到多种功能和建筑的复杂性，提出了可伸缩的膜天花板。本研究是对一个典型的大跨度游泳馆采用可伸缩膜顶棚进行整体建筑性能提升的实验研究。进行了单参数和双参数分析，以量化关键因素。伸缩膜顶棚的安全性能一般采用跌落试验来验证。与其他吊顶系统相比，具有相应的结构优势。此外，长期试验结果表明，膜顶棚可以提高建筑的性能。单参数分析表明，膜顶与空调对温度性能的影响相似。温度升高1.56 °C表明膜顶棚的关键影响。在双参数分析中，夏季太阳辐照度和空调的影响不同，导致能耗增加。在冬季，膜和空调的效果相似，可以比太阳辐照和空调节省更多的能量。
Ceiling performance of enclosed large-span buildings, i.e., stadiums, airport terminals and swimming pools, is related to safety requirements, working serviceability and energy demands. Conventional plasterboard and/or aluminum plate ceilings of large-span buildings are potential dangerous under earthquake effects and energy-consuming during normal working conditions. To ensure safety performance and manage energy performance, a retractable membrane ceiling is proposed in relation to multiple functions and building complexity. This study concerns an experimental study on overall building performance enhancement of a typical large-span swimming stadium using retractable membrane ceilings. One-parameter and two-parameter analysis are performed to quantify crucial factors.Generally, safety performance of retractable membrane ceilings is validated using drop experiments. The corresponding structural advantages are provided compared with other ceiling systems. Moreover, long-term experimental results show building performance enhancement with membrane ceilings. In detail, one-parameter analysis indicates similar effects of membrane ceiling and air conditioning on temperature performance. A temperature enhancement of 1.56 °C demonstrates the critical influence of membrane ceilings. For two-parameter analysis, different effects of solar irradiance and air conditioning in summer result in more energy consumption. In winter, similar effects of membrane and air conditioning can save more energy than that of solar irradiance and air conditioning.
