Design and construction of complex large-span structures
Published in Kok Keong Choong, Mustafasanie M. Yussof, Jat Yuen Richard Liew, Recent Advances in Analysis, Design and Construction of Shell and Spatial Structures in the Asia-Pacific Region, 2019
The structural members of the gridshell are made from S355 steel plate cold formed to a triangular cross-sectional shape (width = 180 mm, depth = 230 mm) with one longitudinal weld seam as shown in Figure 1.5. The structural members were then hot-finished to reduce the influence of welding residual stresses. Since the modern code did not provide any guidance for designing triangular members, a test program was carried out to investigate the flexural and buckling resistance of the triangular gridshell members of various plate thicknesses (8, 10, and 12 mm).

A gridshell, such as the one shown in Figure 8.1 andpage 88, is essentially a shell with its structure concentrated into individual members in a relatively fine grid compared to the overall dimensions of the structure. The members may be short in length and only pass from node to node, or they may be continuous, crossing each other at the nodes. The grid may have more than one layer, but the overall thickness of the shell is small compared to the overall span.
Design and fabrication of smooth poly-hypar timber gridshells

A shell is a structure that gains its strength and stiffness through its inherent shape. A gridshell is a shell with large openings in it in a manner that allows the remaining strips or grids to behave structurally as a shell (Harris et al. 2003). Timber has been used as a key construction material in gridshell because of its availability in nature, less environmental impact and low torsional stiffness to allow bending and twisting of laths.
