对既有膜结构的受力性能进行判定评估对于决定既有膜结构是否能够继续使用至关重要。对上海地区某一展览馆的屋面膜结构材料进行了力学性能试验研究,并对试验结果进行了统计分析,对其是否可以继续使用做出了基本的判断。研究表明,该建筑物屋面膜材仍可继续工作,既有膜结构材料的使用寿命与其所处环境密切相关,同时提出了对既有膜材料老化程度的判断方法和评估既有膜材剩余生命的研究思路。
Determining the force-bearing properties of an existing membrane structure is crucial to determine whether an existing membrane structure can continue to be used. The mechanical properties of roofing membrane materials in a exhibition hall in Shanghai area were studied and the test results were statistically analyzed to make a basic judgment on whether they can be used or not. The research shows that the roofing membrane of the building can still work continuously. The service life of the existing membrane structure material is closely related to the environment in which it is located. At the same time, the method of judging the aging degree of the existing membrane material and the evaluation of remaining life of the existing membrane material Research ideas.
