第一类是由一个平面桁架，有两个到两个正交的空间桁架，正交斜桁架，两个斜对角网格和网格三至四种形式；
第二类是由四个锥体细胞组成，有四个正方形的金字塔空间网格，是把四个对角线的正方形的金字塔空间网格，四，五种网格板四和四星形网格网格；
第三种是由三角形的金字塔单元组成，它由三种类型的三角形金字塔空间桁架、时间三角形的金字塔空间桁架和蜂窝形的三角形金字塔空间桁架组成。壳式空间桁架结构分为主圆柱壳结构、球壳结构和双曲抛物面壳结构。
空间桁架结构分为钢网架、钢筋混凝土网框架和由钢和钢筋混凝土组成的组合网架。
The first class is composed of a plane truss, with two to two orthogonal space truss, orthogonal diagonal truss, two oblique diagonal grid and grid three to four forms;
The second class is composed of four pyramidal cells, there is four square pyramid space grid, is put to four diagonal square pyramid space grid, four, five kinds of grid board four and four star shaped grid grid;
The third kind is composed of the triangular pyramid unit, which is composed of three types of triangular pyramid space truss, the time triangle pyramid space truss and the honeycomb shaped triangular pyramid space truss. Shell type space truss structure is divided into the main cylindrical shell structure, spherical shell structure and hyperbolic parabolic shell structure.
The space truss structure is divided into a steel net frame, a steel bar concrete net frame and a combined net frame which is composed of steel and reinforced concrete.
