摘要:

为了更好地张拉平面薄膜结构,研究其张拉悬索体系,从理论上证明了要使空间平面薄膜结构处于无褶皱状态,其最优的边界应为圆形.提出一种新型的内外部悬索联合张拉方法,给出了此张拉方法下各部分悬索张力的计算方法,并考查了边界跨数对结构的轴压的影响,发现奇数跨时支撑结构所受的轴压相对较小.通过与传统张拉方法的比较,这种新型膜面张拉方法,在固定膜面尺寸、不固定膜面跨数和不固定膜面尺寸、固定边界单跨跨度这2种情况下,所需拉索的截面面积和质量均相对较小,因此,内外部联合张拉方法不仅更易于折叠打包,而且可在一定程度上减小结构的质量.通过计算发现在支撑结构发生变形时,联合张拉方法可以减缓膜面褶皱的出现.

Abstract:

Tensional cable system was investigated to tension the plan membrane structure better. It is theoretically proved that the circle is the optimal shape of boundary cable to make space membrane structures wrinklefree. A new tension method with both inner and outer cables was proposed. A specific method to calculate all the cable's tensions on this condition was given. The influence of boundary span number on the structure's axial pressure was examined and it was found out that odd span numbers will produce smaller axial pressure. Compared with the conventional tension method, the section area and weight of cables needed in the new tension method are both less under the two situations of fixing the dimension of the membrane, not fixing the span number and not fixing the dimension of the membrane, fixing the single span of  the boundary, so that this new method can not only make folding and packaging easy, but also reduce the mass of the structure to a certain extent. Moreover, the new method can alleviate the emergence of membrane surface wrinkle.
