Retractable membrane ceilings for enhancing building performance of enclosed large-span swimming stadiums

摘要

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 degrees C demonstrates the critical influence of membrane ceilings. For two-para-meter 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.
