1.前言彼谢尔尼克无铁件网状筒拱是装配式木结构,筒拱组成整齐的方格或菱形格式拱面,在外观上和内力作用上都是有良好的效果。其网片几何尺寸直接影响到网格的组成是否整齐,特别是其中网片的上边缘斜度f_1及网片侧面边缘的端部斜度f_2。因为这些尺寸的差误是累积的,所以很小的误差,会使拼装结果产生很大的差别,故对此尺寸计算,在设计时要特别注意。关于网片几何尺寸的计算法,在苏联卡尔生等著的木结构一书中已有详尽的 1. Introduction Pensilnik’s iron-free mesh tube arch is a prefabricated wooden structure that has a neat grid or diamond-shaped arch surface with a tube arch that has a good effect both in appearance and in internal forces. The mesh geometry directly affects the composition of the mesh, especially the upper edge gradient f_1 of the mesh and the edge gradient f_2 of the side edge of the mesh. Because these size errors are cumulative, so a small error, will make a great difference between the assembly results, so the size of the calculation, pay special attention to the design. The calculation of mesh geometry has been exhaustively written in a book by Woods et al.
