Design and Analysis of Oval Arch Center with Two Joints for Plastic Tent

塑料大棚两铰椭圆拱架设计与分析

Because the main arch and the center line of the bridge in the horizontal projection is misaligned, the deformation and stress distribution of the bridge are very complex.

主拱肋轴线水平面内的投影与桥梁中心线的不重合，全桥的变形和受力情况都很复杂。

After simulation test and study on the construction of long span stone arch bridge, it is understanded that the combined effect between arch ring and arch center formed in advance is clear and the stress of arch ring is closely related to the process of construction.

施工模拟试验表明，特大跨径石拱桥在分环分段砌筑时，先期形成的拱环与拱架的联合作用明显，拱圈应力与施工过程密切相关。

In addition, research was made on 6 types of arch configuration such as three center circle, logarithm spiral curve, parabola, hyperbola, ellipse and the general quadratic curve.
