這條桅桿下面由幾條鐵索結結實實地綁著,上面有條鐵支柱,用來支撐這面巨大的布帆。Suspend - dome is a new multiplex structure system composed of single - layer spherical latticed shell above, prestressed cables below and braces bars used to link them. compared with single - layer latticed shell and cable dome, suspend - dome can cross a larger span economically and reasonably
弦支穹頂( suspen - dome )是由上部的單層球面網殼,下部的預應力環索和斜索以及聯系二者的撐桿組成的一種新型的復合結構體系。The influence of some design parameters, such as density of net, rise - span ratio, height of strut, prestressing tension of cable, are analyzed, some economical and reasonable optimized parameters were gotten
分析了網格密度、矢跨比、撐桿長度、鋼索預應力值等設計參數對弦支穹頂各項性能指標的影響,得到了經濟合理的設計參數取值范圍。At first, after the dynamic characteristics of the plane and the spatial supporting systems were studied, fore some steps fixed frequency and shape of vibration were gained. secondly, several design parameters which influence the dynamic characteristics of this kind system were discussed, including pre - tension value in the cable, cross - section of the cable, cross - section of steel - bar and form change. some applied decisions were found
首先,對平面和空間索桁支承體系的自振特性進行研究,得到體系的前幾階固有頻率和振型形式;進而探討了索的預拉力、拉索截面面積、撐桿截面面積、形狀改變(撐桿長度l )等主要設計參數對體系自振特性的影響,得出了一些有益的結論,為體系設計和施工提供意見和依據;最後,對體系的風振特性進行了分析,用幕墻風荷載規范對幾種索桁支承體系形式進行風荷載計算。分享友人
