Inhaul cable type curved bar wind bracing connecting structure between arch bridge arch ribs
The invention relates to an inhaul cable type curved bar wind brace connecting structure between arch bridge arch ribs, the structure comprises a curved bar wind brace, an inhaul cable, an auxiliary arch rib and a main arch rib, the axis of the main arch rib is a plane curve, the axis of the curved bar wind brace and the axis of the auxiliary arch rib are space curves, the projection of the curved bar wind brace and the axis of the auxiliary arch rib on the horizontal plane is an arc curve, one ends of the main arch ribs intersect at the center of the bridge cross section, the other ends of the main arch ribs extend to the two sides of the bridge cross section, one ends of the auxiliary arch ribs are connected with the intersection ends of the main arch ribs, the other ends of the auxiliary arch ribs are connected with the extending ends of the main arch ribs, the curved bar wind braces are connected with the adjacent auxiliary arch ribs, and inhaul cables are connected between the adjacent curved bar wind braces. Compared with the prior art, the problems of additional deformation and additional stress caused by directly and independently using the curved bar as a wind brace are solved.
本发明涉及一种拱桥拱肋间的拉索式曲杆风撑连接结构，该结构包括曲杆风撑、拉索、副拱肋和主拱肋，该主拱肋的轴线为平面曲线，所述曲杆风撑和副拱肋的轴线为空间曲线，在水平面上的投影为弧线曲线，所述主拱肋的一端交汇于桥梁横断面的中心，另一端延伸至桥梁横断面的两边，所述副拱肋的一端连接主拱肋的交汇端，另一端连接主拱肋的延伸端，所述曲杆风撑连接相邻副拱肋，相邻曲杆风撑之间连接有拉索。与现有技术相比，本发明改善了曲杆作为风撑直接单独使用导致的附加变形和附加受力问题。
