A triangular grid shell is a spatial truss structure similar to a flat gridshell, consisting of bars arranged in a grid pattern according to certain rules and configured as a shell structure. It combines the properties of both trusses and shells. Its force transmission is primarily achieved through tensile, compressive, or shearing forces in two directions within the shell, transmitted point by point. This structure is a space structure that has received considerable attention both domestically and internationally, with significant development prospects. The grid shell structures include single-layer grid shell, prestressed grid shell, plate-cone grid shell, rib-ring cable-supported grid shell, and single-layer cross cylinder grid shell, among others.
