国家大剧院屋面系统承载性能试验研究

Experimental Study on Loading Properties of the Roofing System of National Showplace

国家大剧院的屋面系统包括结构层、防水层和装饰层。防水屋面板采用铝镁锰合金板 ,装饰层通过连接件固定于屋面板的板肋上。外部荷载主要由屋面板承担 ,进而传递到檩条上。通过试验研究了屋面系统在各种主要荷载作用下的承载能力 ,为工程设计提供了依据。

The roofing system of National Showplace consists of framework, damp-proof course and layer of decoration. The aluminum alloy deck is used as a rainproof roofing boarding. The layer of decoration is fixed on the rib of the roofing boardings by using the fastenings. The load is supported by the roofing boardings and is transferred to the purlines. The loaded property of the roofing boarding under all kinds of load is studied by the loaded tests. The results of the test are useful to engineering design.
