Cross cable dome structure
The invention discloses a crossed cable dome structure, and belongs to the field of large-span space structures. The structure is formed by sequentially arranging and combining a plurality of annular space crossed cable truss structures inwards and upwards in a layered mode. A basic stress unit of the crossed cable dome structure is of a plane cable truss structure and is specifically composed of a ring beam, a prestress inhaul cable, a vertical supporting rod and other components. The annular space crossed cable truss structure is formed by arranging and combining plane cable trusses in a mutually crossed and centrosymmetric mode. The prestressed inhaul cables in the crossed cable dome structure are crossed with one another; all the prestressed inhaul cables are provided with multiple effective standby load transmission paths; if one of the prestressed inhaul cables fails, the other prestressed inhaul cables crossed with the failed inhaul cable can share the load, and the internal force of the structure is redistributed, so that the further spreading of the structural damage is prevented. The crossed cable dome is ingenious and novel in structural form, light in self weight, large in rigidity, reasonable in structural stress and high in application value.
本发明公开了一种交叉索穹顶结构，属于大跨度空间结构领域。它由多个环状空间交叉索桁架结构依次向内、向上分层布置组合而成。所述的交叉索穹顶结构的基本受力单元为平面索桁架结构，具体由环梁、预应力拉索、竖向撑杆等构件构成。本发明中环状空间交叉索桁架结构由平面索桁架以相互交叉、中心对称的方式布置组合而成。交叉索穹顶结构中的预应力拉索彼此交叉；所有预应力拉索均具备多重有效的备用荷载传递路径；如果其中一条预应力拉索失效，与失效拉索相交叉的其它预应力拉索会分担荷载，结构内力重分布，从而阻止结构损伤的进一步蔓延。交叉索穹顶结构形式巧妙新颖、自重轻、刚度大、结构受力合理，具有较强的应用价值。
